PAE Kernel won't boot

I am looking for anyones opinion here. I have a Gigabyte GA-MA78GM-S2H motherboard with a AMD Phenom 9600 CPU and 2x G.Skill 4GB DDR2-1066 PC2-8500 memory kits (total of 8 GB). I also have a HighPoint 3120 RAID controller with 2x WD Raptoer 150 GB 10K SATA drives.

When I install OpenSUSE 11 with all the memory in the machine the PAE kernel is installed and the installation goes fine. I reboot and the kernel seg faults when it attempts to mount the volumes (using LVM).

I have tried many things including running the SLED memtest (the opensuse one hangs - one clue) for 100 hours with no issues/errors. I know it is strange that the opensuse memtest hung but it is also strange that the SLED one worked fine. Last evening I pulled all but one memory stick out - so the machine now has 1x 2 GB memory stick - the machine boots fine. I put a 2nd stick in the kernel seg faults.

I booted with 1x memory stick installed and then installed the default kernel. I can now install all the memory again but obviously the kernel only sees 3 GB.

My question is - I’m not sure what Gigabyte is going to tell me if I call them but I’ll try. I wanted to post here and see if anyone has any bright ideas :-). I would hate to go try a different mboard but may have to. BTW - I booted the machine successfully with each of the 4 memory sticks in the machine singularly so I’m relatively sure the issue isn’t a bad memory stick.

It could be the mboard is just flakey … ?

After talking to Gigabyte I’m going to try a different brand of memory … we’ll see

Update :

  • I have purchaed OCZ memory - same problem
  • I have replaced the motherboard with an Asus one - same problem

Has anyone found this problem previous. As mentioned previous if I pull out 1 memory stick and boot with only 2 GB or RAM the PAE kernel will boot fine, I can then install the default kernel, put in the 2nd memory stick and boot the default kernel but only see 3 GB or RAM.

Does anyone think the CPU is bad? The processor is the only thing I have not replaced :frowning:

Hi & welcome!

My first suggestion would be to go for a 64 bit OS install. Espesially if you are using 8 GB of RAM!!

The main issue with using 64 bit, is to get flash working…
Other than that you can install 32bit libraries so most of your 32 bit only applications should just work.
Also the 64bit flash issue in firfox should be resolved with openSUSE 11.1 and you would also be putting the 8GB to good use!

So I would say : go 64bit & let us know how that goes?

Cheers!
