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. > > 6. Script to replicate the problem > lvcreate -s -n oscopy -v -l 100%FREE /dev/secret/root 2>/root/savefile '-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' ?
