2.0.35-pre6 is still missing some lines of code from Jumbo-9, that are needed
for adequate Cyrix CPU detection.
Here is what I get on a Cyrix MII, with 2.0.35 + Jumbo-9:
processor : 0
cpu : 686
model : M II @ 233.86MHz +/- 0.01MHz
vendor_id : CyrixInstead
stepping : 2.8, core/bus clock ratio: 3.5x
fdiv_bug : no
hlt_bug : no
f00f_bug : no
fpu : yes
fpu_exception : yes
cpuid : yes
wp : yes
flags : fpu de tsc msr cx8 pge cmov mmx
bogomips : 233.47
I think it's clear enough that 2.8 is the stepping, and 3.5x is the core/bus
clock ratio.
Similarly, one gets improved CPU detection for the AMD K6 CPUs, and late Intel
CPUs (but without the core/bus clock ratio detection, since this is only
available on Cyrix CPUs).
As for 2.1.115+: Rafael Reilova maintains this code, but he is away for 3
weeks on vacations. Please report any problems to his email:
<rreilova@ececs.uc.edu> and he will fix/patch the detection code as needed ASAP.
Oh, and about the random CPU lockups: as mentionned by Alan Cox, we don't have a
kernel patch to solve that kind of problem. :-) There are many good sites on
the Web that discuss these hardware problems: Tom's Hardware Site, Anandtech,
Tweakit, etc...
