Attach full -vvvv trace.
Hmm bugreport talks about 2.6.35 kernel.
My first suspect would be the 'Debian way' of handling udev rules - handling
differes from the upstream solution and must be tracked and fixed on Debian.

'-vvvv'
Attach also 'changes' to udev rules from the upstream solution.
Probably udevadm monitoring output would be also useful.
Any cookies left unfinished 'dmsetup udevcookies' ?
