Summary: smbfs not does not survive a S3 suspend/resume cycle
Kernel Version: 2.6.9
Distribution: debian testing
Hardware Environment: dell inspiron 8600, gf5200
self compiled kernel 2.6.9 with S3_late_bios patch from http://www.loria.fr/~thome/d600/
binary nvidia driver 66.29
Problem Description: With the patch from http://www.loria.fr/~thome/d600/ and temporarily
stopping several services and modules, my laptop suspends to the S3 state without any problems.
After resuming, everything works fine except the open smb connections. Accessing to a samba
resource (smbd 3.0.8) results in a smb_add_request timed out error (see dmesg). Doing an ls in a
mounted directory returns a Input/output error.
Workaround: kill all applications accessing the samba resource and rmmod smbfs before
suspending the system. Without unloading the smbfs module BEFORE suspending to RAM, a
reboot is necessary to access to the smb resource again.
please make the smbfs module suspend-to-RAM safe.
Steps to reproduce:
- edit a document located on a mounted samba share
- suspend the system to the S3 state
- try to access the document, application will hang
