A couple kernel updates later, the kernel still panics on resume, but I have made a couple new observations.
It is not nvidia. I have removed the proprietary driver and still could not resume, although the symptom was slightly different: with the nvidia module installed, the panic is indicated by caps lock and scroll lock flashing together, then the machine reboots. Without nvidia, it just hangs forever without any indication of what happened. It is not wpa_supplicant (although I see this error tightly associated with the "can't resume from suspend" category of discussions: pm-suspend.log:Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or directory https://bugs.launchpad.net/ubuntu/+source/linux/+bug/995486 http://ubuntuforums.org/showthread.php?t=1941346 (have seen it reach the desktop stage and crash there a couple times) https://bugs.launchpad.net/ubuntu/+bug/993598 (and plenty more) I have blacklisted my wireless interface (iwl3945) and tried to suspend without it; the result is the same. Panic without any visible trace. It may be a simple co-incidence that all these people also have troble with wpa_supplicant , but definitely a regression, and a relatively recent one (5-6 weeks). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1018015 Title: Regression: the update including linux-image-3.2.0-26-generic breaks suspend on Dell m4300 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/1018015/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
