PROBLEM: ide-related kernel panic in 2.4.19 and 2.4.20-pre11
Trying to read a copy-protected audio CD (I think Cactus Data Shield 200) with readcd I get a reproduceable kernel panic in 2.4.19 and 2.4.20-pre11. As I can reproduce the bug feel free to ask me any further question, if possible cc me. (Otherwise it will take a little longer) The information I gathered is below. some more files (system.map etc) are on http://www.cborntraeger.de/linux/panic.tgz
cheers
Christian
