Athlon kernel crash (i686 works)

[Marco Berizzi]

I updated my motherboard from ASUS A7V to ABIT KT7A (VIA Apollo KT133A
chipset). The kernel I had (2.4.10) started crashing on boot  usually
right after starting init. I tryed a i686 kernel and noticed it works
OK, so I recompiled my crashy kernel only switching the processor type
and it also worked. Changed it back to Athlon/K7/Duron and it starts
crashing.

I also search the mailing list. My mother board is KT7A series v1.3 with
bios revision 4T (I also try with 3N, same results). K7 at 1333MHz. BIOS
settings are default (except I have disabled all BIOS/video shadow).
After flash I also reset CMOS via hardware jumper.

Is there any solution to this (except compiling kernel for 6x86)?

TIA

There is a patch, that changes an unknown bit in the VIA chipset. You can
find it in the archives (search for "Athlon, Try this" or "athlon bug
stomping")
