We'll need Xen's boot messages (you can obtain them through 'xm dmesg' right after boot completed). We'd like you to try leaving DRM (and if that doesn't help, AGP) out of the picture. For the former, it should be sufficient to re-configure X to not use 3D acceleration. You can verify this after X came up in that the modules i915 and drm aren't present. If that doesn't suffice, you'd need to either blacklist or move away/rename the respective modules under /lib/modules/2.6.25.4-2-xen/. For AGP, you'd need to use the latter method in any case (the modules in question here are intel-agp and agpgart). If forcibly leaving out modules, is is possible that X cannot start up at all anymore, in which case some more re-configuring of X would be needed. Another thing we'd like you to try is enable debugging in the drm kernel module by echoing 1 into /sys/module/drm/parameters/debug. Once done, shut down, and restarted, we'd need the full portion of /var/log/messages pertaining to the previous session (not just the oops portion of it) plus the boot messages (which at this point would be in /var/log/boot.omsg). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Did you try suppressing just drm and i915? The boot.omsg and messages fragment we need to see should be from a boot with all modules enabled, and with DRM debugging enabled prior to initiating shutdown (as described). I take your comment about SLED to say that there you don't have the problem reported here? As cross reference knowledge, would you check whether the drm/i915 pair is in use there? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

With all four modules suppressed, did you reconfigure X so it would still come up (I'm pretty certain it doesn't come up without reconfiguration)?

Not surprisingly X does not start. Sax2 fails with 'module not found': FATAL: Could not open '/lib/modules/2.6.25.4-2-xen/kernel/drivers/char/drm/i915.ko': No such file or directory [drm] failed to load kernel module "i915"

Did you try suppressing just drm and i915?

No.

The boot.omsg and messages fragment we need to see should be from a boot with all modules enabled, and with DRM debugging enabled prior to initiating shutdown (as described).

OK: I booted with all four modules in their usual place, echoed 1 to the drm bug parameter and initiated a shut down. Output of /var/log/messages and /var/log/boot.omsg is in the two attachments.

I take your comment about SLED to say that there you don't have the problem reported here? As cross reference knowledge, would you check whether the drm/i915 pair is in use there?

Yes, they are in use and seem to work just fine:

ssh test uname -a Linux tfkp10 2.6.16.60-0.23-xen #1 SMP Thu May 15 06:38:31 UTC 2008 x86_64 x86_64 x86_64 GNU/Linux ssh test lsmod | grep i915 i915 28672 1 drm 91944 2 i915 The new kernel for SP2 is seemingly heavily patched backwards. A few month ago I tried to install SP1 in this hardware and gave up very quickly.

As you give a Novell email adress: if this PC is of high priority for you it might be more efficient to ask FSC for a sample than me trying to follow your instructions. They are interested to get the thing certified for Linux anyway.

Therefore, getting the exact machine model would be the first option (Daniel), locating one with the same chipset would then be the next fallback solution (Jason/Lynn). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
