This was not an error with WiFi cards, since my computer is a regular desktop and doesn't have one. It was connected with usplash, though. After an update of that package it stopped hanging on boot, but would segfault due to missing theme for my screen resolution (or something in this direction, forgive me if my memory fails me).
A few updates of usplash later I no longer get the lockup during shutdown, but usplash still doesn't work properly (doesn't update during the boot sequence and the picture looks awful). This doesn't sound like the problem the laptop users have, even if they get the same symptoms. My guess is that this bug shouldn't have been merged earlier, because the soft lockup issues seems to be resolved. -- Øyvind Grønnesby -- BUG: soft lockup detected on CPU#0! https://launchpad.net/bugs/60053 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
