I did a fresh install of openSUSE 12.3 on an Inspiron 530N with an nVidia 8400 GS. When watching the messages on booting up I see that it disables IRQ 18 and 19 (having to do with usb something). Everything is extremely slow. Ram is overload quickly. However, when I tried kernel 3.10, the IRQ messages went away and the computer became responsive again, and not using up ram. This smells, and looks like a bug with the 3.7 kernel. I post this for two reasons, 1) to see if others notice this and 2) if there is a solution to this. Using kernel 3.10 presents its own issues, the nVidia module isn’t found and the rt3572usb module isn’t working. I haven’t sifted through those issues yet. I’ll get to that later.
Here’s an Ubuntu thread with a similar problem (as far as the IRQ issue) [ubuntu] irq 18: nobody cared (try booting with the “irqpoll” option)](http://ubuntuforums.org/showthread.php?t=2121013)
The errors regarding the IRQ do match what I see.
Searched through my 12.3 /var/log/messages for “disable”, with negative result for yours.
From the research I have done, it would indicate a hardware issue. But since I have tried other kernels and it works fine, I have to conclude it’s some configuration issue with the 3.7 kernel.
No one else has any insight?

maybe post to the opensuse@opensuse.org mail list…
(i don’t remember if i have seen you there before–so, if you know
all of the following then please excuse my inability to know if you
already know, or not.)
subscribe from here
https://en.opensuse.org/openSUSE:Communication_channels#Mailing_lists
and if unfamiliar with ‘their’ rules read the info linked to as
“Mailing list netiquette” before posting…
i’m guessing someone their might ask you to log a bug (or know it is
already logged (maybe on the kernel list, if not in the openSUSE bug
list)… OH! you might ought to PM jdmcdaniel3, or maybe even better
read though his post on new kernels in the pre-release/beta forum

Ok, so I did some more research and there is a bug for this (which is a relief in a way as I was starting to think it was just me). https://bugzilla.novell.com/show_bug.cgi?id=809810#c0

there has been a lot of ‘strangness’ reported against 12.3…lots…

Just as a side note. The computer is running fine on Sabayon Linux 13.04. If I had to, Sabayon would be the other distro I’d call home, but anyway. I still don’t know what it is with openSUSE 12.3 kernel configuration. I might never know.
