While the system seems to act fine afterwords, the system will not shutdown or suspend and sync commands freeze and become unkillable. A magic sysrq reisub is required to reboot and I believe I've lost some data a few times. Attached is 3 different bug entries, 2 for 2.6.31.8 and one for 2.6.31.12 which I tried hoping it fixed the problem. Reproducible: Always Steps to Reproduce: 1. mount a cifs share 2. umount the cifs share 3. ??? 4.

I should also mention that the cifs share does unmount.
and subsequent mouunt/umount of the same share seem to proceed without error. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The server is running OpenSuse 11.2 as well with samba-3.4.2-1.1.3.1.x86_64, slipped my mind to mention.
Will get around to testing at some point.
Thanks, that is appreciated. I have committed the patch to openSUSE-11.2 repo. You could grab the upcoming KOTD kernel for testing too. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
