I've run memtest a few times already since this making this report. Passes every single time.
No, I can't switch to terminal (using Ctrl+Alt+F1). Even tried Ctrl+Alt+Del to restart & Ctrl+Alt+Backspace to restart Xorg session but keyboard appears entirely unresponsive. Nothing on-screen is clickable. Things that should have on-screen updates (eg, downloads in progress, file transfers) don't. The only thing that's responsive (sometimes) is the mouse. I'll try switching to terminal with that Alt+PrintScreen+R shortcut you suggested next time it happens. I'm not sure I want to blame this on Compiz, but after disabling it I've not had the soft lockups for 2 days now. This is new because I tried disabling Compiz in Hardy and it definitely did not help at all. Just to repeat myself, Gutsy runs perfectly normal on this exact machine. -- Soft lockups in Hardy shortly after boot up https://bugs.launchpad.net/bugs/250837 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
