Re: [Dazuko-help] v3.1.1 causes system hangs & crashes on kernel 2.6.31 (Debian Etch)

[Michael]

Hi!
I confirming problem with dazukofs-3.1.1 and kernel: 2.6.31similar to
what have been described here.
I use Ubuntu_9.10 with kernel: 2.6.31-14, and I compiled dazukofs-3.1.1
and followed the instructions in the README-file with no complaints.

>From syslog:
Nov 11 00:31:45 coollin2 kernel: [30127.043408] dazukofs: loaded,
version=3.1.1

When I have installed Avira AntiVir the system crashed and will not boot
up with the dazukofs-module in place:  '/lib/modules/`uname
-r`/kernel/fs/dazukofs/dazukofs.ko'

Se added part from syslog.

I then tried to use your fix with an extra hook in DazukoFS to return an
error when the kernel tries to do this:

http://dazuko.dnsalias.org/files/dazukofs-3.1.1-20091024.tar.gz

But this will not help me. The system will not start with this module in place 
either.
