Kernel oops on x86_64 2.4.27 with 8GB RAM and sata_sil

[Roland Fehrenbacher]

Hi,

I have appended the output of ksymoops obtained from an Oops on an
Opteron Server that has 8GB RAM. The Oops occurs when disc access to a
SATA disk is attempted. The disk sits on a SIL3114 controller. There
is no oops and perfect behaviour if I specify mem=4032M as a kernel
parameter. Anybody got an idea what is going on?

Many thanks,

Roland
