Bug#623212: ncpfs: Causes kernel tracelog with kernel 2.6.38
Subject: ncpfs: Causes kernel tracelog with kernel 2.6.38
Package: ncpfs
Version: 2.2.6-8
Severity: normal
Hello,
since using linux-image-2.6.38-2-amd64 from testing I observed kernel
tracelogs when trying to access a Novell drive mounted via ncpfs. The
following text was found in /var/log/syslog

I observed this on one of my boxes. On this box the problem is pretty
reproducable. A different one had undetermined networking problems, was
featuring a system crash (but no trace in syslog) and there very several
problems in umounting ncpfs mounted Novell volumes.
I'd volunteer to provide any debug info which might be needed to track
down this problem.
Kind regards
Andreas.
