Hi all,
It seems that I cannot get 2.3.2x running reliably on my dual P5/133. The box generally dies after a few minutes of high load (kernel build with make -j4 is one of my favorites), while 2.2.12 is just rock solid...
This time, I was able to save 2 oops before pressing the Big Red Button(tm) :
ksymoops 0.7c on i686 2.2.13. Options used -v /usr/src/linux/vmlinux (specified) -K (specified) -L (specified) -O (specified) -m /usr/src/linux/System.map (specified)

Just in case it might raise someone's eyebrows, the kernel is compiled on a dual celeron box (much much faster...) with CONFIG_M586TSC set.
.config and other stuff avaible upon request...
