Description David Botzer 2011-03-07 09:42:37 UTC
Description of problem:
I get Kernel Panic 
When my WLAN disconnect, and than tries to reconnect without user intervention
(where the last line of the message says cifs....)

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. create a mount to local server at work (CIFS, see attached fstab)
2. Connect to WLAN, 
   I can connect successfully to a WLAN from my laptop.
   I can connect successfully my VPN (TLV)
   I can connect successfully both to Internet & RH Intranet.

3. try to cause the connection to be disconnected on its own - 

Actual results:
Kernel Panic, requires hard reset

Expected results:

mount using cifs to remote server

Comment 4 Jeff Layton 2011-03-07 15:22:09 UTC
Sadly, the log messages don't contain the full traceback, but if it's oopsing in cifs_show_options then this is almost certainly a duplicate of bug 629085. Closing as such -- the fix should be in 6.1.
