This works like a charm. Thanks. Maybe for inclusion in 2.4.23-pre6?

If someone cares enough. I got tired of pushing that patch since 2.4.21.

Marcelo, can this be included in 2.4.23-pre6? It fixed the 0 KB L2 cache for
Pentium M cpu's.

Hello List,
I just noticed this:
devilkin@precious:~$ cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 9
model name : Intel(R) Pentium(R) M processor 1600MHz
stepping : 5
cpu MHz : 599.511
cache size : 0 KB
fdiv_bug : no
hlt_bug : no
f00f_bug : no
coma_bug : no
fpu : yes
fpu_exception : yes
cpuid level : 2
wp : yes
flags : fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 tm pbe tm2 est
bogomips : 1196.85
Somehow, the cache size doesn't seem to be correct. Spec info tells me that this cpu
has indeed a 1024kb cache.
Any patches to test?
Thankx
Jan
