Since I upgraded my processor to a Cyrix/IBM 6x86 M-II 300, I get many
OOPSes in my log. Before that I had a P166MMX and I never had any problems
at all (actually I didn't know how a OOPS looks like).
In the last 24 hours I had 4, 3 of them seemed to be X related. Then I
updated X from version XFree 3.3.2 to 3.3.3.1. The 4th was while I was
playing mp3. The system was almost idle.
/proc/cpuinfo says:
processor : 0
vendor_id : CyrixInstead
cpu family : 6
model : 2
model name : M II 3.5x Core/Bus Clock
stepping : 8
cpu MHz : 233.031908
fdiv_bug : no
hlt_bug : no
sep_bug : no
f00f_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu de tsc msr cx8 pge cmov mmx
bogomips : 232.65
I don't know how well this type of processor is supported, but I think,
my problems must have something to do with it.
/proc/version says:
Linux version 2.2.1 (root@die-macht) (gcc version 2.8.1)
I attached the 4 OOPSes below, parsed by ksymoops.
