I have recently switched over from Gutsy to Jaunty (fresh install), and the system started to freeze randomly, although the REISUB combination usually worked.
After downgrading to 2.4.27, the system ran stable again for several days, but eventually locked up too. Then I tried the standard Jaunty kernel (2.6.28-11-generic) once more, and the system was mostly stable again (froze "only" twice in the past week). However, after the last freeze yesterday, it has become unusable again; starting Gimp and Firefox froze the system every time (with and without plugged network cable, with and without acpi option, with and without activated swap), although I had used these programs a lot over the last week without problems. These freezes were also hard freezes, ie. the REISUB combination did not work, Caps Lock did not blink, and even the mouse cursor was frozen. I am now using the PPA mainline kernel 2.6.27-02062710-generic again, and this seems to work; for now. As far as I remember, I have not installed anything in the past few days, so it has been essentially the same system all the time, and the computer has been running flawlessly with Gutsy for over a year now. The computer is a Dell Optiplex 745 (Intel Core Duo, ATI Radeon X1300/X1500), and I am not using any proprietary drivers. ** Attachment added: "dmesg.txt" http://launchpadlibrarian.net/26955481/dmesg.txt -- Computer hard locks randomly with ubuntu jaunty https://bugs.launchpad.net/bugs/355155 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
