--- Begin Message ---Package: linux-image Version: 2.6.26-2-amd64 Severity: important Hardware: A machine with a pair of 2.5" SATA disks, configured with three RAID1 devices (/dev/md1, /dev/md2, /dev/md3), reports a soft lockup as shown below. The system is running Debian Linux 2.6.26-2-amd64, libc6 2.7. It has a custom card (requiring the mfb and memmgmnt drivers as shown in the log). This card shouldn't affect the disks in any way. The system contains a hardware watchdog; and the long soft lockup caused the watchdog to expire, resetting the system. On reboot, we weren't able to detect any signs of trauma on the disks, so we're left with a diagnosis of a software lockup in md1_raid1 which took the box down due to a watchdog expiry (i.e. this problem is critical for the system in question). 2011-07-03T00:57:02-07:00 testhost kernel: [2500677.138796] md: delaying data-check of md1 until md0 has finished (they share one or more physical units) 2011-07-03T00:57:02-07:00 testhost kernel: [2500677.142796] md: delaying data-check of md2 until md1 has finished (they share one or more physical units) 2011-07-03T00:57:02-07:00 testhost kernel: [2500677.142796] md: delaying data-check of md1 until md0 has finished (they share one or more physical units) 2011-07-03T01:17:22-07:00 testhost kernel: [2502418.212841] BUG: soft lockup - CPU#0 stuck for 235s!

--- Begin Message ---Version: 3.4.1-1~experimental.1+rm Debian 6.0 Long Term Support has now ended, and the 'linux-2.6' source package will no longer be updated. This bug is being closed on the assumption that it does not affect the kernel versions in newer Debian releases. If you can still reproduce this bug in a newer release, please reopen the bug report and reassign it to 'src:linux' and the affected version of the package. You can find the package version for the running kernel by running: uname -v or the versions of all installed kernel packages by running: dpkg -l 'linux-image-[34]*' | grep ^.i and looking at the third column.
