Me too.

Toasted my 2.0.34 (pre-whatever -- it's the stock RH5.1 kernel). Didn't
touch my SMP (ooops -- I _always_ forget :) 2.1.100 for i686.

processor : 0
cpu family : 5
model : K6 (166 - 266)
vendor_id : AuthenticAMD
stepping : 2
fdiv_bug : no
hlt_bug : no
sep_bug : no
f00f_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr mce cx8 mmx
bogomips : 398.95

Since we have K6 people here, perhaps someone would care to tell me what
the right processor type for the K6 is? make config says it's an i686,
but /proc/cpuinfo says i586...

Matthew.
