unable to boot current

I have been trying to update to latest current without luck. It seems
something changed in init and fsck_ffs.
When I boot a newer kernel than March 16. I get problems at fsck. What I see
is:

<snip>
Mounting root from: ufs:/dev/ad0s2a
start_init: trying /sbin/init
pid 105 (fsck_ufs), uid 0: exited on signal 8
pid 106 (fsck_ufs), uid 0: exited on signal 8

and then it hangs.

I installed the latest fsck_ffs (matching the new kernel) which seems to have
removed the fsck problems since it doesn't exit with signal 8 any more. 
However it still hangs after trying /sbin/init.

I read /usr/src/UPDATING which doesn't say anything about fsck_ffs og init.

I have no problems booting with the kernel build on March 16.

Any suggestions.
