Public bug reported: On my HP EliteBook 6930p, running Ubuntu 11.10 (Oneiric) suspend and resume does not work properly.
Sometimes on suspend, and sometimes on resume, the machine completely freezes. Symptoms are: - black screen - cannot switch virtual terminals (aka Ctrl+Alt+F1) - no response on Caps-Lock (Caps light does not change status) - cannot reboot using Ctrl+Alt+Del - kernel hotkeys do not work (e.g., Ctrl+Alt+SysRq+S does not lead to disk activity) - sometimes, kernel 'boot' hotkey (Ctrl+Alt+SysRq+B) still works (but sometimes not) - no flashing Caps lock (i.e., not a kernel panick) It doesn't always happen, and it seems like the chances are higher if I use the machine more intensely. For example, yesterday after a day of video editing, the first resume already froze. Normally, I can get a number of suspend/resume cycles before the freeze. cat /proc/version_signature gives: Ubuntu 3.0.0-12.20-generic 3.0.4 lspci attached. According to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/420424, a BIOS upgrade *might* fix this, but I'm not too happy doing that for a 'might fix'... Not having windows and running HP's window's only flash tool sounds hara kiri to me. That bug is identical to this one, except that it's now set to no-fix due to being filed against an 'unsupported series' (does that mean my laptop model?). And I cannot change that bug's status. I'll put a link there to this one, too. When I next have a couple of minutes spare time (LOL!) I'll try the instructions at https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume and report back here. I've been having this very same problem for a long while (I don't remember when - but I just came across a post http://ubuntuforums.org/archive/index.php/t-1604695.html where they describe it first appearing in lucid - that sounds about right for me). So it was in lucid (10.4) , maverick, natty, and now oneiric (11.10). In the meantime, I would be very grateful for any additional hints/tips. ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/887171 Title: [Hewlett-Packard HP EliteBook 6930p] suspend/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/887171/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
