So when the test program is running, you are able to log in, start the
web browser, etc, without any problems?

It sounds like when you do the test program, you are only using a test
mountpoint of DazukoFS (as stated in the README). Could you mount all
the DazukoFS mounts you normally would mount and run the test program?
That should cause the same log in and web browser problems.

It would be helpful if we could reproduce the problem without AVIRA
running. If DazukoFS is mounted on /home and you run the test program,
it should trigger the same problem.

Could you also list which directories you are mounting DazukoFS onto?

$ grep dazukofs /etc/fstab
$ mount | grep dazukofs

And I assume you are indeed using DazukoFS 3.1.1:

$ dmesg | grep dazuko

The kernel crash shows the stack trace. It would be helpful if you
could at least write down the function names in that trace.
