https://bugzilla.novell.com/show_bug.cgi?id=238572 Summary: SCSI Subsystem Locks-up Machine Product: openSUSE 10.2 Version: Final Platform: x86 OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: jim@edwardsj7.com QAContact: qa@suse.de My system has the root, "/", and "/home" directories on two different SCSI drives on the same chain of an Adaptec 29320 (U320) card and they are using the AIC79xx driver version 3.0. From time to time the system will cease to function and the SCSI activity indicator LED will stay on at 100% (usually it only flashes very briefly) and the machine becomes unresponsive. Maybe after a long time it will seem to return, but really the SCSI drives are off-line and even a restart fails back to what looks like an "init 3" screen with "login" displayed, but nothing is accepted. A system hard RESET, or power off and on, is required to restore functionality. The ensuing reboot displays a large number of transactions being replayed for the "/" RFS, 800+ is not unusual, but nothing for the ext3 (when it was RFS it had some transactions). It seems that this lock-up is triggered by things that try to move a lot of data over the SCSI bus, like "mkisofs" or some other large file transfers. Moving "/home" to an IDE drive did not help. "/" is on an RFS version 3.6 partition and "/home" is on an ext3 partition (it was RFS, and changed to ext3 with no effect). The same system hardware (AMD Athlon XP 2500+ etc.) has been running Suse 9.0 successfully with no such problems, and still can, so it seems to me to be likely to be related to the newer drivers (version 9.0's are much older, version 1.3.something, I think), possibly in association with RFS ???
