I just tried blanking a CD-RW with the latest -git tree. The machine just became unresponsive and then froze. When it became unresponsive the clock in GNOME still displayed the current time but I could not focus any windows anymore. Then I had to hard reboot the machine. The logs say nothing. I repeat: nothing.

Does anyone have similar problems?

Instead of rebooting, just wait for the blanking to finish. My guess is that your burner and hard drive are both on the same ide channel, and so you can not access the disk while the burner is blanking. If this is the case, put each drive on their own ide channel.

It takes hard drive access to switch window focus? Yes, thats a question.

Depends on your programs and RAM. If the program you try to switch to (or, say, part of X or your window manage) is swapped out for some reason, then yes, changing focus may cause said program to hang until it can swap the data in. Usually that's a small fraction of a second, but if your IDE bus is waiting for a burn, then it could be the duration of the burn.

Cheers,
Kyle Moffett
