2.6.18/Reiser3 - lost directory and strange warnings

[Martin Lorenz]

panic arose about an hour ago...
a whole directory tree was suddenly gone and every try to access it resulted
in an i/o error

the log shows this:

a reboot into maintainance mode and fsck of the partition brought the dir
back without data loss (pffffew!)

but I am still concerned, what has happened here?

a grep on my syslogs revealed quite a few similar warnings which I obviously
diden't notice. - attached wich a few lines of context

see http://www.lorenz.eu.org/~mlo/kernel/?C=M;O=D for more
