Hi,
on my Cyrix 6x86L (notice the L) I've got the problem that it doesn't get
identified as a Cyrix processor. Instead it is treated as a common 486.
I think the problem is that the cpuid feature is not enabled after booting. So
init_cyrix which enables the cpuid feature is never called.
As a bad hack I've set the this_cpu pointer to cyrix in
common.c:identify_cpu():
this_cpu = cpu_devs[X86_VENDOR_CYRIX];
Who is responsible for x86 CPU detection?
Cheers,
Gregor

Hans Peter Arvin? Andrew Balsa?

Can you identify which kernel version broke this for you?
Thanks,
