Hello all, I'm sorry it took us so long to get back to you. We had hardware issues with said machine and had to replace it. So now we're facing these crashes again. Hardware: As in http://bugzilla.kernel.org/show_bug.cgi?id=14579 Software: Debian Lenny, with Kernel 2.6.32(.4, I believe). Adaptec 52445 for the RAID, LSI SAS1068E for the tape library. We tested with aacraid driver versions 24900 and 2461, mptfusion versions 3.04.12 and 3.04.13. What works: Booting system from the RAID, dd if=/dev/zero of=/dev/backup/drv2 bs=1M (/dev/backup/drv2 is the second tape drive within the library) No crash (at least not within 12 hours) And subsequently: dd if=/dev/sdb of=/dev/null bs=1M No crash (at least not within 12 hours) When doing the two dd's *simultaneously*, the machine *crashes* reproducibly after a maximum of 10 minutes. The machine also crashes reproducibly when transferring data from the RAID to the tape. Stacktrace taken from a serial line is attached. Any help would be really appreciated.
