Hi Soeren, We encounter here a deadlock with a quite new ATA 120GB disk. The disk worked good for about 3 weeks, but now we have a strange problem. There seems to be one defective file on the disk. fsck doesn't find it, and if I do a cat file > /dev/null The machine locks completly. Serial console is dead, no remote DDB via ALTBREAK possible anymore, no panic message, just freezed. The evil began after we installed this ATA disk. It only happens for one file on this disk, the other 10000 files are fine. Do you have a idea why break into the debugger doesn't work anymore ? Even if we have a hard-error on the disk, this should still work, shouln't it ?
