Package: cifs-utils
Version: 2.5.5-1


I have Debian Wheezy (stable) installed with all the latest updates on a Lenovo T400. I have cifs-utils installed and the T400 connects to network shares on a windows pc.

When the laptop wakes up from suspend to ram and I then try to access a CIFS shares, it freezes. Any program that tries to read/write to the CIFS share freezes. It stays frozen for about 5 minutes before finally working. This happens 90% of the time. Before upgrading to Wheezy, I never had this problem. The first request and any subsequent requests for a CIFS share freezes the program trying to access the share. For an example, if I start the laptop but only access the CIFS share 5 hours later.....it will cause the freeze. It will only unfreeze and work after a 5 minute freeze...and then all requests start working fine until the next time I suspend to RAM.

Here is the error output from syslog:

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
