Message-ID: <417DD81B.2090802@aknet.ru> (raw)
Hello.
When I am trying to access some files
on an SMB server, I get this in the log:

and then the system is unstable, so that
I have to reboot.
This happens with all 2.6 kernels I tried
(from something like 2.6.2 to 2.6.9).
The only reference to the similar problem
I can find, is this:
http://lkml.org/lkml/2003/5/22/49
This bug is really nasty and I guess I was
waiting for too long for it to get fixed.
Any hints how can I get more info out of
it, or how can I start debugging it?
