I have traced this down to only occurring while in battery mode on my Samsung X360. It occurs seemingly random, but it is accompanied by a hard drive spindown. I have had this issue since 9.04.
Currently the only workaround that reduces the probability of a hard lockup is setting: hdparm -S 0 /dev/sda I have tried to simulate this by messing with -Y and such in hdparm, but I can't seem to hard lock it manually. The seemingly random lockup may be associated closely about the time I would get a 40% (the first "warning") battery life. Hope this helps. -- hard lock (hang) after a few minutes with APIC enabled https://bugs.launchpad.net/bugs/659705 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
