UPDATE: I re-installed Ubuntu 12.10 from scratch on a new hard drive, no virtualbox installed yet and I keep getting both false and real GPU lockups. So it seems like a problem in the 3.5 kernel, which carries through to the 3.8 kernel. Would the problem likely go away if I changed computers and used one with a real graphics card instead of the on-board one? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1154591 Title: [sandybridge-m-gt2+] False GPU lockup IPEHR: 0x3b00 IPEHR: 0x0b140001 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1154591/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Ok, to draw things together again: I originally submitted Bug #1153587, where you identified the missing TLB invalidate as the reason and suggested that an upgrade to kernel v3.8 would fix it. I installed Kernel v3.8.2 but the problems continued. You asked to provide /sys/kernel/debug/dri/0/i915_error_state, which I was not able to provide, so instead I submitted this bug report here, hoping that the relevant information would be added automatically. Based on the current crash report you again identified the missing TLB invalidate as the reason and claim that Kernel v3.8 would fix it. In your last comment about Bug #1153587, you mentioned that something might be wrong with rc6. Would deactivating rc6 be a way to break out of this loop?

The error state here says Kernel: 3.5.0-26-generic, so I would check the grub menu to make sure it was defaulting to the older kernel. To get past #1153587, we need i915.i915_enable_rc6=0 - the root cause behind those is still a mystery. Some have been linked to a severe GPU hang, some have been linked to needing a BIOS update, most seem to have no obvious cause. And you are also hitting the semaphore issue, so i915.semaphores=0 to workaround that issue as well. I'm sorry, you seem to have found all of our outstanding issues. :( -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1154591 Title: [sandybridge-m-gt2+] False GPU lockup IPEHR: 0x3b00 IPEHR: 0x0b140001 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1154591/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Thanks for putting my issues in context with the rest. However, I'm still confused, as the 4th line of the above bug report says: Uname: Linux 3.8.2-030802-generic x86_64 I currently have the i915.i915_enable_rc6=0 set (see e.g. https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1153587/comments/9) and I had the i915.semaphhores=0 before. How can I set both at the same time? I set it in the /etc/default/grub as GRUB_CMDLINE_LINUX_DEFAULT=quiet splash i915.semaphores=0. Can I add a second GRUB_CMDLINE_LINUX_DEFAULT? I am also wondering if the Virtualbox kernel additions might be causing problems. And another thought is that there may also be a problem in apport-gtk, as it really keeps bombarding me with more and more gpu hung apports if I try to submit the first one. If I click on Cancel instead, it leaves me alone.

And vbox is not without issues ;-) I'm not sure about the inner workings of apport myself, so I'll let that be. Maybe Bryce could check it over?

Unfortunately, an hour later, apport catapulted me back onto this site. So this is with the 3.8.2 kernel and with the line GRUB_CMDLINE_LINUX_DEFAULT=quiet splash i915.semaphores=0 i195.i915_enable_rc6=0 in grub. This time, I cannot find any error messages relating to i915 in the syslog or kernel.log. Not sure why apport sent me to this site here again. I now remembered that I installed some extension to apport in order to help capture kernel errors. All these error reports are generated by /usr/share/apport/apport-gpu-error-intel.py. It contains the line: attach_file_if_exists(report, '/sys/kernel/debug/dri/0/i915_error_state', 'i 915_error_state') Unfortunately: root@machine:/usr/share/apport# more /sys/kernel/debug/dri/0/i915_error_state no error state collected Any more ideas how I could shed light into this?
