after upgrading a AMD Athlon 1133C CPU to Atlon 1200C my linux kernel
crashed at boot.
Nothing else was changed.
I have a kernel 2.4.5 compiled for Athlon/...
After disabling #ifdef CONFIG_MK7 in arch/i386/lib/mmx.c (the kernel uses
now the generic page functions) all things seems ok.
Does anybody nows about a layout change for the AMD Athlon 1200C?
A Bug or a feature?
I'm not an assembler freak so i don't now what the movntq command do...

Regard,
Axel

This may be WAY off, but just outa curiosity what mobo have you got?
@ Work we had a batch of MSI K7T Turbos that gave us nothing but
problems for Athalons 1.2 GHz and above, but worked perfectly for chips
less then 1.2. The prob. was that something was wrong with the
voltages, and the chip was getting to hot, so the system shut down. By
the sounds of it, this is not the problem, but all the users who had
these problems were using windows, so I havent seen the reactions under
linux. Best of luck then!

Win98/Win2000 have no problems on the mobos. I have found this error on
Epox kta3+ and elitegroup K7VZA. Athlon 1133C runs ok, two 1200C crashes at
boot time (linux).
It crashed downclocked to 800Mhz too.
I thing, many linux users don't use kernels compiled for Athlon CPUs.
Standard distribution kernels are more general.

I have a Athlon compiled kernel running now, I had to upgrade the BIOS
first to get it to run.
Compileing worked, but when I booted the kernel, nothing but kernel
panics.
The standard 686 kernel work fine.

Mobo: QDI KT7E-A Athlon 1.2 GHz
