Thanks for the kernel output. This is helpful.
Could you answer the following questions?
1. Is /home the only directory you have DazukoFS mounted on? If no,
could you only mount DazukoFS on /home to see if the problem still
exists? I suspect that the problem may not be /home, but instead
another directory such as /tmp or /var.
2. The following problem should occur when no Dazuko-based
applications are running. (No AvGuard, no Dazuko test program.) Is
that correct?
3. Could you provide the output of "mount | grep dazuko" so that I can
see exactly where DazukoFS is being mounted?
