I'll try to dig a bit deeper on my own. That sounds like a good exercise. This isn't a big issue anyway but just could get fixed. > Do you get any information on the crash (maybe in the system log file, or on > the console when doing insmod/rmmod on a text console)? No, computer was so dead that nothing was written to disk. All I got was nice panic message begining of which managed to scroll off the screen and some leftovers in buffer being played in the loop. I didn't take a picture but that should be easy to reproduce. I'll be without access to computer for next few days. I'll try to reproduce this once I'm back (not sooner than Sunday evening).
