Re: 2.4.[<=6] kernel has Cyrix 'coma' bug?

Rob,

My CPU is a bit different than yours (sorry for not posting this with
the original message).

[root /root]# cat /proc/cpuinfo
processor       : 0
vendor_id       : CyrixInstead
cpu family      : 4
model           : 1
model name      : MediaGX 3x Core/Bus Clock
stepping        : 2
fdiv_bug        : no
hlt_bug         : no
sep_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : -1
wp              : yes
flags           :
bogomips        : 59.59

I posted my .config file if anyone is interested.  MTRR is not set.
