Comment 3 for bug 894543

System configuration is an Intel G41 motherboard with 4 300GB SATA drives, each with a small boot section and a much larger partition devoted to being part of a RAID5 array.

Thus /dev/md0 is built from the sd[abcd]2 partition each of which is approx 250GB. The resulting /dev/md0 device is an LVM2 physical device. Sometime around the 2.6.35 kernel this configuration became unstable with the boot being extremely slow and a udevd: worker exited unexpectedly error.

Once finally booted, the system has been working normally.

Both update-grub and update-initramfs -c -k all have been run since the last update/configuration change.
