Hi,
I use a quad opteron machine based on the fedora core 2 test 3 release.
I compiled a kernel 2.6.6-rc3 myself and the machine crashes when
mounting the rootfs. I tested kernel 2.6.6-rc2 with exact the same
.config and it works fine, the same with kernel 2.6.6-rc1.
I send you my .config, the syslogs and the output of ksymoops.
Regards,
Alexander
