The situation is greatly improved, but in 1 out of ... say 12 reboots the Kernel still hangs at the DVD-detection. Someone worked around this by placing a DELAY() somewhere in the code (can't remember right now, search the archives). It also seems that it doesn't happen with bootverbose. Turning on debugging seems to avoid it for you, because the kernel is slower and thus not fast enough to win the race against the CD-drive (Note: I'm only guessing!). Let's see what S=F8ren has to say about it, perhaps an additional DELAY() is needed for borken drives :( Ulrich Spoerlein --=20 PGP Key ID: F0DB9F44 Get it while it's hot!
