Public bug reported: I installed a fresh copy of Intrepid on my system on the 30th, and over the past two days I've had several random lockups that force me to do a hard reboot. I can still move the mouse, but clicks are not registered, and keyboard input does not work at all. Hence, I cannot change to a TTY or Ctrl+Alt+Backspace. I did not experience this kind of thing with Hardy.
After a lockup, when I check /var/log/kern.log and /var/log/messages, this output is always the same: Nov 2 19:16:24 nomadsland kernel: [ 598.734960] Uhhuh. NMI received for unknown reason b1 on CPU 0. Nov 2 19:16:24 nomadsland kernel: [ 598.734970] You have some hardware problem, likely on the PCI bus. Nov 2 19:16:24 nomadsland kernel: [ 598.734973] Dazed and confused, but trying to continue This is quite random. It has happened while browsing in Firefox, typing an email in Thunderbird, mounting an external drive, and changing viewports with Compiz (vanilla as installed by Intrepid). I can't force it to reproduce... I can't see any pattern. My hardware is: Inspiron 6000 laptop, intel 2200 wireless, X300 ati card. I checked other reports of freezes but none were exactly the same. The problem may be related to this old bug, however: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/116752 More info to follow. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- Random freezes completely lockup system in Intrepid, inspiron 6000 https://bugs.launchpad.net/bugs/292751 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
