https://bugzilla.novell.com/show_bug.cgi?id=241787 ------- Comment #13 from jolz@gmx.de 2007-05-03 00:31 MST ------- Seems to be the same problem here. But the kernel also crashes, when the users is currently not really using CIFS, but has active mounts (the mounts via pam_mount do not seem to make troubles.) in this case, the user did nothing related to CIFS (i.e. he was not working on a CIFS mount.). The User just logged in (pam_mount mounted 5 CIFS-shares without problems) and wanted to enter his kwalled password. The "Call Trace" is quite similar, so i assume, it's the same problem.
