Alan> As I said media players need a way to turn it to no retry
I just ran into this with a scratched CDROM and the program 'grip'
which ended up requiring a reboot of my 2.6.8 kernel to get back
control of /dev/cdrom on my system. Needless to say, I wasn't very
happy about this.
I really think that we need some way to keep such deadlocks from
happening. I really dislike having a device lockup a user application
so hard that it can't be exited. There's no real reason we should be
doing this any more. If we have to, let the user kill it and just
have the kernel make it into a zombie, but at least let the user kill
it off.
John
