sorry to forget to post these info's: i am running 
freebsd-current. started with 5.1 release and updated yesterday. 
i removed the debugging stuff from the kernel cause i wanted to 
check the possible performance difference.

i agree but this would be difficult when being unable to reboot the
system :)

i ran: fsck -y /usr and it complains several times (!) about "unexpected
soft-update inconsistency" and "unable to write block" :(

i have not tried an alternate super block yet - i was not sure whether
this could help, could it ?

i used default settings


finally i found out that i can mount /usr readonly so a backup could be
possible (?); creating new ufs2 and restore backup could be a possible
solution (?)
