When Linux vanilla kernel 2.4.34.5 is compiled with -march=c3 (VIA C3)
- kernel crashes after boot on a VIA C3
.config: CONFIG_MCYRIXIII=y
Environment:
System: Linux bongo 2.4.34.5-ARXc3 COHERENT #9-ARX (Build 3359) Fri Jun 8

How-To-Repeat:
compile vanilla linux kernel 2.4.34.5 with CONFIG_MCYRIXIII=y and boot
the kernel on a VIA C3 -> crash
