Is this still reproducible with 3.x kernels? Like from kernel:stable, kernel:head or tumbleweed? (In reply to comment #1) > Is this still reproducible with 3.x kernels? Like from kernel:stable, > kernel:head or tumbleweed? I tried 3.1 (http://download.opensuse.org/repositories/Kernel:/stable/standard/x86_64/kernel-desktop-3.1.0-3.1.x86_64.rpm). Unplugging the device does not crash the computer anymore. However, it still doesn't seem to be quite right. - After having unplugged the device once, it won't work if plugged back in. - The module em28xx_dvb can't be removed manually. The rmmod command just hangs: --- snip --- # lsmod | grep dvb em28xx_dvb 18417 0 cxd2820r 33424 1 em28xx_dvb dvb_core 114318 2 em28xx_dvb,cxd2820r em28xx 113165 2 em28xx_dvb,em28xx_alsa # rmmod em28xx_dvb ^C^C^C^C --- snap --- It seems to be hanging in I/O somehwere: --- snip --- $ ps aux | egrep 'rmmod|USER' | grep -v grep USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 11364 0.0 0.0 3952 536 pts/9 D+ 10:35 0:00 rmmod em28xx_dvb --- snap --- I'm not sure how to proceed. I guess the original problem (Kernel Oops) has been solved. Should I open a new ticket? (In reply to comment #2) > $ ps aux | egrep 'rmmod|USER' | grep -v grep > USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND > root 11364 0.0 0.0 3952 536 pts/9 D+ 10:35 0:00 rmmod > em28xx_dvb I think it still crashes. Could you attach dmesg output when it is in this state? I apologize for the slow response. I simply don't always have the hardware to test with at hand. AFAICT the dmesg output doesn't give much information. But trying to rmmod one of the dvb-t modules shows an info (INFO: task khubd:28 blocked for more than 480 seconds.) in syslog with a call trace (provided below).
