http://bugzilla.kernel.org/show_bug.cgi?id=14579 Summary: Devices disappear; on bus reset machine hangs; on I/O machine hangs Product: IO/Storage Version: 2.5 Kernel Version: Linux version 2.6.30-1-amd64 (Debian 2.6.30-5+techfaklenny1) (sfrey@xxxxxxxxxxxxxxxxxxxxxxxx) (gcc version 4.3.2 (Debian 4.3.2-1.1) ) #1 SMP Sat Aug 15 11:20:08 UTC 2009 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: blocking Priority: P1 Component: SCSI AssignedTo: linux-scsi@xxxxxxxxxxxxxxx ReportedBy: sfrey@xxxxxxxxxxxxxxxxxxxxxxxx Regression: No Created an attachment (id=23729) --> (http://bugzilla.kernel.org/attachment.cgi?id=23729) lspci -vvv output On our soon-to-be primary backup machine with an Adaptec 52445 (for the disk pool) and an LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (for the Tape Library), we see random failures: On Tape-IO (using btape from bacula), a few minutes into the writes, the changer device and both tape devices disappear from the system. Rescanning the bus sometimes helps, but sometimes results in a hardy freeze. On Tape-IO, a few minutes into the writes, the system freezes. lspci -vvv, lsscsi and dmesg and /proc/modules are attached, this might also be related to #14577 as it's the same machine. Attached is also a screenshot of the oops we saw on the last crash that happened durign a btape run. The system uses stock Debian/Lenny with a custom built 2.6.30.5 kernel. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
