Hi, This week, a new kernel was available for quantal : 3.5.0-25-generic, and used. After 1 day 2:59 uptime and usual activity, another oops occurred.
To help figure out a possible culprit, here is a summary of recent activity. * using for days a heavily loaded firefox (total of 27 windows and 91 tabs, session restored after reboot to change kernel) * opening a 16000x16000 JPEG, namely http://www.eso.org/public/archives/images/large/eso1309a.jpg * plugging Galaxy Nexus smartphone on USB * observing USB mouse suddenly not working, but mouse laser light still on * unplugging-replugging USB mouse. Mouse laser light now off. * observing system freeze for about 5 seconds (probably music, too) * observing switch to text mode and oops text (like described in original bug report) * switching VTs using Ctrl-Alt-Fn to regain X session access * observing firefox taking 100% of one cpu core and memory 3.2GB (varying, 2.9GB after a while, still 100% cpu) * not observing signifiant system slowdown or led showing disk thrashing * machine has 6GB physical RAM + 6GB swap, using 4.7GB RAM and virtually no swap (58MB) * observing rhythmbox has stopped playing when oops occurred. Pausing/playing changes the "play/pause" status in rhythmbox window, but time indicator does not move and no sound produced. * opening another firefox window to write this very report * while I type, rhythmbox resumed playing (after about a minute without touching it) On previous bugs occurrences, firefox also was heavily loaded a Galaxy Nexus plugged recently on USB. Firefox was also loaded all the week, though probably a bit less, and phone is plugged/unplugged more than daily. Attached dmesg from command line because /var/log/dmesg does not contain oops text. Considering to try latest kernel soon. Hope this helps. Thank you for your attention. ** Attachment added: "dmesg_from_command_line.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1132129/+attachment/3552845/+files/dmesg_from_command_line.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1132129 Title: Kernel crash and oops since 3.5.0-24-generic (3.5.0-23 ok).
