SubjectRe: OOPS in 2.4.21-pre5, ide-scsi
Date
Hi

strange looks alot like the ones i have seen though the whole 2.4.x tree.

this was discussed before somebody said they would send a patch myself
and sombody else were going to test it but the patch never happens.
From what i can work out an error occurs on the cd drive and the request
queue is then empty and the ide-scsi driver then attempts to access the
reuest queue that doesnt exist i never did manage to find out
where the request get removed from the queue though.
