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
16:41:33 CEST 2007 i686 i686 i386 GNU/Linux
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu VIA C3 -march=c3
configured with: /home/axel/p/rpm/BUILD/gcc-4.2.0/configure --prefix=/opt/gcc4
--exec-prefix=/opt/gcc4 --srcdir=/home/axel/p/rpm/BUILD/gcc-4.2.0
--enable-shared --enable-languages=c,c++,objc
How-To-Repeat:
compile vanilla linux kernel 2.4.34.5 with CONFIG_MCYRIXIII=y and boot
the kernel on a VIA C3 -> crash
