Public bug reported:
Binary package hint: cryptsetup
Yesterday I upgraded from ubuntu 9.04 to 9.10 and I experience the following
problem when booting.
(everything was fine in 9.04)
What I expected to happen:
I expected to the boot luks passphrase entering procedure to be the same as in
9.04. Boot with usplash disabled, prompt for passphrase appears, I enter the
passphrase, boot procedure continues.
What happened instead:
I have / on a lvm volume (not encrypted) and /home on a lvm volume (luks
encrypted).
(probably not important, but mentioning it anyway: I have /tmp as a symlink to
/home/tmp, so /tmp may not be usable until /home is mounted)
Without usplash enabled it is almost impossible to enter the passphrase. It
looks like multiple processes during the boot process start fighting for the
input/output. I could not even use the recovery shell, it stopped
working/accepting input within 10-20s. (ctrl-alt-del works, and reboots the
machine)
After I read on launchpad that entering the passphrase will only work
with usplash enabled I was able to enter the passphrase, but I have to
enter it 3 times before it is accepted and boot continues.
The problem is worse when the machine is cold-booted, because swap uses
/dev/random as a key, I assume it takes some time to acquire enough
entropy for the key but this causes usplash to enter text mode, and
entering the passphrase becomes impossible. In this scenario the
recovery shell is functional and allows me to manually unlock the luks
partition.
