From Bugzilla Helper: User-Agent: Mozilla/4.78C-MyBrowser [en] (X11; U; Linux 2.4.9-13-jk1 i686) Description of problem: I have two cdroms on one bus, originally both mounted through ide-scsi. Putting a load on both disks at the same time (with rsync) gave an oops with the message "Aiee, killing interrupt handler". According to EIP/System.map, its crashing in ide_build_sglist. (I believe I need a serial connection to get the full oops message here, or copy by hand which I didn't do) It crashes reliably, but not immediately. Mounting one drive ide-cd and one ide-scsi still crashes. Appears to work OK to load one cdrom via ide-scsi and leave the other cdrom unused (or it at least greatly reduces the odds of crashing.) Mounting both with ide-cd works OK, but is not very nice if you want be able to use cdrecord on one of them. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Mount two cdrom's on one IDE bus, 2. On both drives, run something like: "rsync -avc /mnt/cdrom remote:/xxx" or probably any command to put a heavy read load on the drives 3. Actual Results: Kernel Oops in ide_build_sglist Expected Results: Not crashing... Additional info: I am using the standard 2.4.9-13 i686 kernel. System is a Dell Dimension 8200 with pentium 4 2.0 GHz processor. (Maybe it's doing something too fast?) IDE controller is an intel 82801BA. Maybe there's some ide parameters one can use at boot time, but this would probabyl be more of a work-around than a fix. I can some more debugging if you give me a hint.
Seems to be OK on newer kernels. Since nobody else has reported this problem, I'll mark it as CURRENTRELEASE.
