Bug#353457: linux-source-2.6.15-4: CIFS_CLIENT locks system with multiple, parallel file access
Justification: renders package unusable
This bug is easy to reproduce: try to run synaptic against a cache that is accessed via
cifs. synaptic /or dpkg?/ would download multiple files in parallel - with kernel 2.6.15-4
this almost instantly locks your system until rebooted.
The bug is not completely new: but in previous CIFS versions the "desaster" probability was
far less (in 2.6.14 it rarely happend).
# 2 (for information and to say something friendly about CIFS):
The CIFS server side is less broken in 2.6.15-4 than in 2.6.14: CIFS still cannot handle
the situation where a device gets unmounted while being accessed via CIFS (automounter).
The improvement is that you no longer need to reboot the server - but it still hangs
for a while filling the log with it's complaints until giving up. In 2.6.14 you always had
to reboot the kernel in such a situation.
