Tyan s2885 dual 246, 2Gb RAM crashes on kernel 2.6.10

[Valerio Aimale <vga@seirad.com>]

Hello,

I have a Tyan s2885, (latest BIOS 2.04) with 2 246 opterons and 2Gb of
RAM. 

The 2.6.10 kernel
(kernel-image-2.6.10-9-amd64-k8-smp_2.6.10-4_amd64.deb)
crashes on startup, while loading the initrd disk.

This is a short excerpt captured from the serial port

-----------------------------------------------------------------

I've tried all possible kernel option (numa=off, noacpi, nolapic, notsc,
acpi=ht). Nothing worked.

Kernels 2.6.9* and 2.6.8* are all fine.

Regards,

Valerio
