Description Gordan Bobic 2010-05-23 10:51:07 UTC
Description of problem:
Approximately half the time, udev hangs for a long time at startup, and eventually produces many messages like this before eventually timing out:

  /sys/devices/virtual/block/md126 (10745)
  /sys/devices/virtual/block/md127 (10746)
  /sys/devices/virtual/block/md126 (10747)
  /sys/devices/virtual/block/md127 (10748)
  /sys/devices/virtual/block/md126 (10749)
  /sys/devices/virtual/block/md127 (10750)
  /sys/devices/virtual/block/md126 (10751)
  /sys/devices/virtual/block/md127 (10752)
  /sys/devices/virtual/block/md126 (10753)
Wait timeout. Will continue in the background.             [FAILED]

Version-Release number of selected component (if applicable):

How reproducible:
Approximately 50% of the time.

Steps to Reproduce:
1. Set up rootfs on md RAID5
2. Reboot
Actual results:
udev startup stops until timeout.

Expected results:
Fast startup without timeouts and error messages.
