Hi all :)

After (hard) power cycling a computer, running linux-2.6.3*, the
filsystem (ext3) sould be recovered at boot. However I get the following
message from the kernel. I have tried booting the redhat
kernel-2.4.20-30.9 - but with the same result.

* The kernel was patched with our Umbrella LSM module, but however _no_
changes were made to the filesystem.


Cheers,
KS.
