Should I > not be using atapicam with 8.0? This one is old one. I get it sometimes since 7.0 (perhaps, 6.x affected too) on my desktop and it sometimes repeats with 8.0-BETA2 too (GENERIC kernel). It's some kind of race condition because it does not always hang, but often enough to be annoying. There should be a media in drive to make it happen, blank or written. Eugene Grosbein
