Default Re: Frequent lockups after 2.6.19 upgrade (or so I believe)

It isn't very deterministic. It triggers while I'm using my X server normally. I think both times it got triggered while using my X terminal mrxvt. In any case, it seems to be a bug that appears after a day and a half of uptime (during which the X server needs to be running, If I shutdown every day it doesn't seem to trigger).

I haven't tried yet. I just tried switching from AGPgart to NvAGP and it happened also. I'm currently running with NvAGP 0. I will post an update in a few days if all goes well.

I am, but the last update to the BIOS is quite old and ASUS just added support for newer processors.
I was getting a few ACPI and APIC errors, so I tried playing with that. I tried booting with noapic and setting interrupt mode from APIC to PIC (and that is visible now from /proc/interrupts). This changes were made before the last freeze, so they didn't affect anything.

As far as I can tell, no. If it freezes again I'll disable that and try.

BTW, does the kernel oops report that I've attached help to locate where the NULL dereference is being made?

Thank you for the response,
