Results so far, using the Raring "linux" package builds. This bug is first introduced in the transition from 3.7.0-7.15 (good; the last 3.7-based kernel; based on mainline 3.7.0) to 3.8.0-0.2 (bad; the first 3.8-based kernel; based on mainline 3.8.0-rc3).
Quite sadly, there are 12407 commits inbetween those two tags. I will try to commit-bisect those (should take about 15 steps), but with all the building involved this may take a while to complete. Thank you for your patience. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1173074 Title: 10de:0652 [Samsung NP-R710-AT01NL] Nouveau freezes after suspend/resume in Ubuntu 13.04 / 3.8.0 Status in “linux” package in Ubuntu: Incomplete Status in Arch Linux: New Bug description: Before updating to Raring yesterday, I first fully disabled the Xorg- edgers PPA (by ppa-purge) and was therefore switched back to the Nouveau driver. Then updated my system from Quantal to Raring. Afterwards, I noticed that after a suspend/resume the greeter would not appear or hang completely. I was intermittently able to move the cursor, but the GUI would not respond to hovering or clicking. I did not experience this bug in Quantal with kernel 3.5, but I rather quickly switched to the proprietary driver for performance reasons. I am on a laptop with NVidia GeForce 130M video card on Raring with kernel 3.8.0, no experimental drivers in use. Attached is also a dmesg log from a previous time this occurred, with me trying to recover from the situation by various means - there are a lot of nouveau-related error messages in it. Ctrl-alt-backspace does nothing, SysRq+K does what it is supposed to do but to no avail, restarting lightdm obviously does not help. To reproduce: 1. Boot 2. Suspend 3. Resume Observed behaviour: The greeter does not appear or hangs completely, switching to another VT is initially impossible, after a certain period of time nouveau starts spitting out error messages to the screen and it is then again possible to switch to another VT. Sometimes X randomly restarts and shows the boot-time greeter, where I can log in, but after that the system freezes again.
