Kernel Oops on Alpha Architecture when starting the Xserver.
Whenever I start the Xserver, version 1.6.2 from Debain Unstable, I get a
kernel oops report and the computer crashes hard; no ping response, hitting
the reset button to return to SRM fails. Has caused corruption on disc
partitions on some crashes. This occurs with kernels 2.6.30, 2.6.30.1 and
also a patched version of 2.6.29.x (patched so that I get PCI resource files
under sysfs).
The kernel oops is:
Unable to handle kernel paging request at virtual address 000000000000000c

So, does this indicate a software fault (e.g. inconsistencies in kernel
data structures) or does it imply a hardware fault?

SRM (the equivalent of a BIOS) cannot post the card on startup. But I
have had the card (radeon rv610) post correctly and working in the past
when I compiled the complete 1.5.3 Xserver myself. I had it working
with both the radeon and radeonhd drivers and a 2.6.29.x kernel patched
to support libpciaccess.
Everything went to custard went I reinstalled and upgraded to Debian
unstable.
As an experiment I have removed the Radeon rv610 card and installed a
really old Sis variant video card.
The Xserver now displays a green screen and gets no further. The
machine no longer Oops. Instead the Xserver sucks up near 100% CPU. I
connected to the Xorg process with gdb and got the following backtrace:

There is no -ati card in that machine, its got some SiS card which is
completely
different, maybe its some onboard card or something.

No, you have misunderstood. I removed that Radeon rv610 card (that
caused the kernel oops) from the machine and replaced it with an old SiS
card I have. The behaviour changed: now the Xserver locks up on
initialisation and consumes 100% CPU. The backtrace I provided is with
the SiS card only. I thought it might be helpful to locate the problem
(assuming that we are seeing a different symptom of the same underlying
problem).
BTW, my attempt to CC the xorg mailing list failed. It would seem that
they are too exclusive to allow posting to their email list without
subscription. Putting up such barriers means they won't get bug reports
from such people as myself. Their loss.

My experience:
I have loaded linux on a number of Alphamachines, including the PWS series,
XP100 and UP2000/+. Sometimes the X-erver doesn't work. And it trashes the
whole install. Once that happens, you can chaNGE graphics cards but the
X-serve will not recover, maybe because the kernel is implicated in the whole
train wreck.
I usually just wipe everything clean and re-install with a known good graphics
card.
It wasn't a problem back when Compaq was paying Red Hat to put together the
7.1 and 7.2 distros. There just aren't enough people working on Linux Alpha,
and the whole thing has gotten rickety. IMHO
