(It should run fine on a wheezy/sid system.) Could you retrieve full "dmesg" output from the 3.2.y failure?

Could you retrieve full "dmesg" output > from the 3.2.y failure? 2.6.32 has never heard of this GPU, so the i915 module doesn't initialize. The X server exits immediately, saying no device was found, but doesn't crash. The kernel panics on trying to reboot, but the stack trace shows a bunch of EFI-related functions, so it's probably unrelated. But let's make a note that yes, I installed with EFI boot, which is probably a lot less tested than legacy BIOS boot. I haven't tried if it is happier with BIOS boot, I could do that tomorrow if you think it's important. 3.2 behavior is now similar: i915.ko doesn't know the GPU, and X just exits because i915 isn't there. My last tests were with a 2.19 X driver, presumably the update to 2.20 made the 3.2 crash go away. -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".

Support for this GPU seems to have been added by cc22a938fc1d drm/i915: add Ivy Bridge GT2 Server entries which was merged in 3.4-rc2. [...] > This is on an Ivy Bridge Xeon E3 with GPU.

So I now think the problem is in the kernel. Can you get a trace of the crash using a serial console[1] or netconsole[2]? If so, please report this to bugs.freedesktop.org, following instructions from "http://intellinuxgraphics.org/how_to_report_bug.html";, and let us know the bug number so we can track it.

I got netconsole working, and some messages came through (I replugged a USB device to trigger some), but nothing when it crashes. I don't have the cabling here for serial (it's only a pinheader on this board), but I could get it next week if that's what it takes. -- To UNSUBSCRIBE, email to debian-kernel-requ...@lists.debian.org with a subject of "unsubscribe".

Ok, thanks. Please attach a full log from netconsole from booting and reproducing the problem. (It's ok if it doesn't say anything interesting at the crucial moment.) If you can get the corresponding Xorg log, that would be interesting, too.

I have seen the same problem on one of my own systems and investigated a little way, but didn't reach a conclusion yet.

One more test and then we should take this upstream: does a boot without attempting to start X work ok? Do you get a working framebuffer console? You can try this by either choosing the "recovery mode" option from the grub menu or by adding 'text' as an extra word (no quotes) at the end of the kernel command line. Either way, please report this upstream following instructions from http://intellinuxgraphics.org/how_to_report_bug.html and let us know the bug number so we can track it. The upstream maintainers will want a kernel log with the boot option 'drm.debug=0x0e' appended as an extra word (no quotes) at the end of the kernel command line.

Either way, will do that tomorrow or so. Thanks! 0xe == 0x6 | 0x8 prints a little more debug info which I don't think is too important but it's what I've seen them ask for on bugzilla lately.
