Unfortunately I have not been able to see any oopses. Thanks a lot for doing this! Our backups run every other night and usually write 15-20GB to tape, and it was 2 weeks before we hit this. So it's not very easy to reproduce. They ran again last night (with the patch) without incident. There's one more thing that might be interesting: the morning before this crash happened, this machine mysteriously rebooted for no apparent reason. There was nothing in the logs. Unfortunately, the BIOS screen wipes out the last ~24 lines of serial console output on reboot, so all I can say is that if anything was printed it was much less than 24 lines. There are other machines on the same UPS so it wasn't a power glitch. And it had just had an uptime of 170-some days with 2.6.11.3 (which had some annoying bugs but was stable), so it's not exactly prone to random reboots... I didn't think it was worth mentioning since I knew nothing about what happened, but I noticed that it happened exactly one hour after the 6:37am cron job (updatedb etc.) - the same one that caused it to crash the next day after the oopses during the backups. Might it be related? Let me know if there's any more info I can provide. -ryan - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
