Please send me a CC of your reply, I'm currently not reading this list. Thanks in advance. After installing the 2.0.36 kernel (previously using the 2.0.35 one) I noticed SCSI problems while doing backups on a DDS2-DAT streamer. After backup up about 3.0-3.5 GB of data the driver started screaming about: Dec 10 10:35:25 myrkr kernel: scsi : aborting command due to timeout : pid 1593026, scsi0, channel 0, id 2, lun 0 Read (10) 00 00 2d 98 e3 00 00 01 00 Dec 10 10:35:25 myrkr kernel: scsi : aborting command due to timeout : pid 1593027, scsi0, channel 0, id 2, lun 0 Read (10) 00 00 24 42 01 00 00 01 00 Dec 10 10:35:26 myrkr kernel: SCSI host 0 abort (pid 1593026) timed out - resetting Dec 10 10:35:26 myrkr kernel: SCSI bus is being reset for host 0 channel 0. Dec 10 10:50:28 myrkr kernel: scsi : aborting command due to timeout : pid 1899023, scsi0, channel 0, id 2, lun 0 Read (10) 00 00 2e db c8 00 00 01 00 Dec 10 10:50:28 myrkr kernel: scsi : aborting command due to timeout : pid 1899024, scsi0, channel 0, id 2, lun 0 Read (10) 00 00 3a 7d 04 00 00 01 00 Dec 10 10:50:29 myrkr kernel: SCSI host 0 abort (pid 1899023) timed out - resetting Dec 10 10:50:29 myrkr kernel: SCSI bus is being reset for host 0 channel 0. id2 is one of my hard discs, complete information will follow. While these messages are generated the whole system stand still for about 5 seconds (I was working in X11 this time, even the mouse cursor didn't move). If I use the linux kernel 2.0.35 (with the aic7xxxx 5.0.19 driver) I never got this problems, I'm able to complete my ~4GB backup without any problems. Back in 2.0.34 I was able to crash the machine doing backups with the SCB paging option enabled, just in case you're interested. As I see in the options list below, SCB paging is enabled by default (and no longer optional). Maybe this is the source of my problems with this driver. To my application (the backup program afbackup 3.1) the above problems are reported as media error on the tape, the author told me that he would expect some better indication of general scsi problems. If you need additional information please tell me, I will try to support you in solving this problem.
