Are you still seeing this with kernel-debug of 3.9.0 or the soon to be finished 3.9.1? *** This bug has been marked as a duplicate of bug 928542 *** |
Description of problem: CIFS response on my system(s) can be VERY slow. All the CIFS shares are listed in /etc/fstab with the options "_netdev,nofail," so, theoretically, the presence of the locks should not be a problem that would, or should, cause an "oops" in the kernel. Note that this is NOT a fatal problem. I don't know why it gets raised to the level of a "kerneloops."
