    Nothing unusual in your "top" output, your A4 APU is no roaring beast but the problem seems not to be there.
    BTW "top" here shows just two empty lines before useful output, maybe the gap you see is part of your problem.

    tsu2 gave an useful hint pointing to IOAPIC, maybe you need to experiment with different parameters; your MoBo might have a different layout compared to those in the original Ubuntu thread. I can't be of any further help here, never touched an A4 APU (yet), sorry.

    The disk light constantly flashing and the snail-booting might point to a nearly full /root partition or other disk problems.
    Posting the output of "df", or of "btrfs filesystem df /" if you are using btrfs for /root, might help if you see something odd.

    OK, here is the readout for both of those. I know this APU is not exactly the best out there, but when my Pentium 4 machine died unexpectedly (motherboard stopped POSTing but still gets power), I had to get something and this was the best machine I could afford. Sadly, about 2 weeks after getting this one I priced up components to build similar and could have just built my own with an A8-7600k, 2x8GB DDR3-1866 and a mobo that has USB3 and SATA3 all for about $100 less than I spent on this prebuilt machine. Lesson definitely learned!

    Code:

    Constant disk activity can point to a bad/weak sector(s) run smartctl. Get details on parameters with man smartctl and yes brand new disks can go bad

    Last time I did try smartctl.. and unless I did something wrong with the command, it was absolutely useless. said it would take up to an hour to run, but it never even ran as far as I could tell.

    Code:
    linux:/home/justin # smartctl --test=long /dev/sdasmartctl 6.3 2014-07-26 r3976 [x86_64-linux-3.16.7-29-desktop] (SUSE RPM)Copyright (C) 2002-14, Bruce Allen, Christian Franke, www.smartmontools.org
    
    
    === START OF OFFLINE IMMEDIATE AND SELF-TEST SECTION ===
    Sending command: "Execute SMART Extended self-test routine immediately in off-line mode".
    Drive command "Execute SMART Extended self-test routine immediately in off-line mode" successful.
    Testing has begun.
    Please wait 60 minutes for test to complete.
    Test will complete after Wed Feb 24 02:49:24 2016
    
    
    Use smartctl -X to abort test. linux:/home/justin #
    Beside for that, I did run a test outside of OS from Ultimate Boot CD. The program I ran (only one that would do anything with this drive) was Vivard 0.4
    First test run showed 8 errors within the first 2% of scanning, but there was also a loose power cable that was causing a voltage drop.
    Second run, with the power cable plugged right and proper voltage, showed no errors at all.

    I do not know what to do, I do not understand one bit of any of this. One thing tells me the drive is IDE bus, another thing says it is SCSI. I look at the drive and it is SATA.
    I'm about to just take a very big hammer to this whole machine. Never had this kind of problem on any older system that has the legacy BIOS... only once they screwed things up with that **** UEFI ****. Windows is garbage just like the idiot who made it! And capitalism can bend over and get what's coming.

    Rebooted system and instead of getting the normal MSI splash screen I got this instead



    Don't have any clue how it figures a bad overclock since I have NEVER overclocked any computer before and wouldn't even have any clue how to do so.
    I pressed F1, it went into BIOS, I simply clicked saved and reboot. Then it booted normally... still with the same firmware bugs listed and all.

    So looks like I'm stuck dealing with the problem as is since there is no where to get help for free. Learning should not cost anything and especially not be forbidden to those of us who are **** poor!!

    Oh did you set overclocking???

    You can overclock but the settings that works in Windows may not work in Linux because of differences in timings.

    On the other hand it may be a hardware problem????

    A full smartctl can take a long time since it scans the entire disk. try the -a option it gives the history which should point to any trouble with the device

    resetting the BIOS may erase any boot info so the BIOS may not know how to boot the installed OS(s). SO you may have to point it to the right OS to recreate the entry in its memory

    Unfortunately you apparently stumbled on a HW / FW / Kernel problem that affects many, according to Mr. Google, but has no standard fix it seems...
    Let's recap:
    - your CPU seems OK, no odd task eating up your meal
    - your disk partitions seem OK
    - it is normal for a SATA disk to be seen as SCSI (the SW interface) or be connected to the IDE bus (HW interface)
    - your disk HW might or might not be always OK (is the PWR connector fixed once and for all?)
    - an AMD-vi / IVRS / IOMMU problem plagues many over the net across distributions, hints here and there, no standard fix according to my searches.

    I should say that we don't know yet if the latter might be causing the snail-speed of your setup, from what we read so far.
    The errors reported only say that the kernel is trying to workaround what it sees as a faulty BIOS table; but those might affect Input/Output performance and/or prompt servicing of interrupt requests from peripherals (disks, among others).

    If you are not using virtualization (VirtualBox, VMWare, KVM etc.) and unless tsu2 comes up with a brilliant solution
    you might try one or more of the following:
    1) enter the BIOS and disable everything called Virtualization, AMD-vi, AMD-V, and /or labeled IOMMU
    2) add "iommu=soft" to your boot command line (from this thread); you might just hit the "E" key at the boot screen and edit the "Linux" line without rebuilding grub, then hit F10 to boot.

    If your system is still able to boot with any of these and the snail is gone, you might at least have a workable system for everyday work.

    No, I have never overclocked any computer I've ever owned. Wouldn't know how. Besides, if I understand it right, AMD APUs can NOT be overclocked unless they are the ones signified with a k (ex. A6-6400k is unlocked, my A4-6300 is locked)... but I suppose that I could be misunderstanding how that works too.

    I will try those last few suggestions. If those don't help either then I give up with this machine, I don't have the patience or energy to deal with it any longer. I'll just do what I can to scrape up enough extra funding to build a new machine and give this one away to whom ever wishes to deal with it.

    This time I'll make sure to build it myself and that it has USB3 and SATA3 6.0Gbps ports on the motherboard. Then I can use my SSD for booting and it will run full performance. Can't fathom why on earth they are still making motherboards with only SATA2 at best and no USB3 when those are now so readily available, backwards compatible and the new standard.

    *edit*
    In the mean time, I will go back to using my old laptop. It's a Dell XPS M1330 with Core 2 Duo T9300 (2.5GHz/6M/800MHz), 4GB (2x 2GB) DDR2-800, nVidia GeForce 8600M and a 500GB Seagate Momentus (SATA 3.0Gb/s, 16MB buffer/cache).

    So just out of curiosity, is that to say this is only a problem for Linux users? Or would this also affect a Windows 8/8.1/10 install?
    Mainly wondering on account of I had the same problem with it constantly slowing to a crawl when it had Windows 8.1 (pre-installed). Thought I'd go ahead and check out Win 8.1 while it was there. Hated it due to the constant slow downs. So maybe it wasn't even OS related at all to begin with?

    Now I don't even see an edit button for my post(s) here...
    Checked BIOS and there are no such options in any section. I did notice that there's an option for SATA controller that allows for IDE, AHCI or RAID and it is set to AHCI.

    Think I'm definitely going to just build a new system and use a good Gigabyte board. These MSI ones are just junk.
