Web-update -> Unable to boot

[Assar]

Upgraded to 2.0 snapshot Mon 14 Mar, 10:14:08 via web interface.
Unable to boot

FreeBSD/i386 bootstrap loader, Revision 1.1
(sullrich@FreeBSD_8.0_pfSense_2.0-snaps.pfsense.org, Mon Mar 14 10:14:08 EDT 2011)
Loading /boot/defaults/loader.conf
Unable to load kernel!

can't load 'kernel'

Type '?' for a list of commands, 'help' for more detailed help.
OK boot
can't find 'kernel'

[eri--]

Seems like a faulty upgrade file or upgrade process.

[Assar]

The kernel file seems missing.
Which file is about to be loaded?
Should I be able to load it manually?

Update:
A sober thought: This really should have been todays snap. The update really messed up. Full install should work.

Update2:
Latest snap is running since 1 hour.
