Boot device mapped to new name after upgrade to 11.04

[Rune Nordbøe Skillingstad]

Tried a release upgrade to 11.04 yesterday (remote) and the machine never came up after reboot. It could not find the root device.

I got an error message from udevd: inotify_add_watch(6, /dev/dm-1, 10) failed: no such file or directory

But all the open bugs seemed not to fit on my situation.

The grub cmdline had root/dev/mapper/isw_fdadjaege_Volume01 and that device were missing. Instead I found isw_fdadjaege_Volume0p1 and quickly guessed that the missing device no were renamed.

Changed device name in menu.lst, and now my system boot again.

This is the only system I have using device mapper on root, so I'm not able to reproduce. The system were installed as 10.04 and release upgraded to 10.10.

Some info about the system:
