Bruce Evans e5d7d24361 Fixed error handling after a seek error that can't happen. When the ... controller reports a successful seek, it is very unlikely to report seeking to a cylinder other than the one requested, but we check for this, and botched the error handling for the requested_cylinder != 0 case. This error happened when the bug fixed in rev.1.52 of <sys/buf.h> caused the head of buffer queue to change to one starting on a different cylnder - the requested cylinder was found, but it wasn't what we thought we requested. The fix is simply to arrange to reset the state machine. Corruption of the buffer queue seems to only have been a problem in the floppy driver. Other drivers dequeue the head of the queue before doing physical i/o on it, so the corruption at worse broke the elevator sort order. Dequeueing breaks it anyway.		1998-07-18 03:15:33 +00:00
