Comment 26 for bug 444563

This bug also appears when using LVM mirrors at least when resyncing.

For testing purposes I have created six LVM partitions on two physical drives:

sam@karhuherra:~$ sudo lvs -a -o +devices
  LV VG Attr LSize Origin Snap% Move Log Copy% Convert Devices

  home karhu mwi-ao 37.25G 22.16 home_mimage_0(0),home_mimage_1(0)
  [home_mimage_0] karhu Iwi-ao 37.25G /dev/sdb1(5482)
  [home_mimage_1] karhu Iwi-ao 37.25G /dev/sda1(5482)

  opt karhu mwi-ao 2.79G 100.00 opt_mimage_0(0),opt_mimage_1(0)
  [opt_mimage_0] karhu iwi-ao 2.79G /dev/sdb1(4767)
  [opt_mimage_1] karhu iwi-ao 2.79G /dev/sda1(238)

  root karhu mwi-ao 952.00M 100.00 root_mimage_0(0),root_mimage_1(0)
  [root_mimage_0] karhu iwi-ao 952.00M /dev/sdb1(0)

  swap karhu mwi-ao 9.31G 89.09 swap_mimage_0(0),swap_mimage_1(0)
  [swap_mimage_0] karhu Iwi-ao 9.31G /dev/sdb1(2383)
  [swap_mimage_1] karhu Iwi-ao 9.31G /dev/sda1(2383)

  usr karhu mwi-ao 5.59G 100.00 usr_mimage_0(0),usr_mimage_1(0)
  [usr_mimage_0] karhu iwi-ao 5.59G /dev/sdb1(238)
  [usr_mimage_1] karhu iwi-ao 5.59G /dev/sda1(953)

  var karhu mwi-ao 2.79G 100.00 var_mimage_0(0),var_mimage_1(0)
  [var_mimage_0] karhu iwi-ao 2.79G /dev/sdb1(1668)
  [var_mimage_1] karhu iwi-ao 2.79G /dev/sda1(4767)

These partitions will be resynced on every boot, because they have been created using lvcreate -m1 --corelog.

This resync produces several times the error message
udevd-work[***]: rename(/dev//.udev-tmp, /dev//) failed: Invalid cross-device link

Most often the boot is successful, but sometimes it fails in different ways, hangs, fails to bring up bridged networking, fails to autostart virtual guests. Since this is a test setup for a new server and I'm getting all these problems, I'm considering changing to some other distro especially if Ubuntu is giving these problems low priorities.
