Subject: Long delays and keystrokes required - related to disk encryption?

I'm seeing some very strange behavior with 2.6.28-rc2-95-g49fdf67 on my
HP 2510p notebook.

During the boot there are several places where I need to hit a key for the
boot to continue. There are also some very long delays before the next
syslog message is displayed.
The boot does continue and regularly hitting a key helps (but does not get
rid of all delays), but it is a huge regression from 2.6.27.

The delays seem to continue until file systems get mounted.

As the delays start at the point my system asks for the passphrase to
unlock (LUKS) encrypted disks, I suspect it has to do with that.
Especially since hitting a key seems to "trigger" new disk activity.

However, the delays happen _again_ during shutdown, which makes it extra
strange that the system does behave normally when logged in.

During the first boot wireless networking failed. During the second boot,
wireless networking did come up (without any relevant changes).
This gave an interesting extra data point: with wireless the delays on
shutdown started later: after iwlagn gets disabled.

Any ideas?

Cheers,
FJP
