Hm, the same assertion as in <http://bugs.debian.org/637436>. Thanks for pointing out the regression range! I suspect this is fixed by the following patch, which is part of v3.1-rc3 and will probably be included in v3.0.4. Testing (of -rc kernels or of the patch below alone) welcome, of course. :) commit 13589c437daf Author: Steve French <sfre...@us.ibm.com> Date: Thu Aug 18 04:41:55 2011 +0000 [CIFS] possible memory corruption on mount CIFS cleanup_volume_info_contents() looks like having a memory corruption problem. When UNCip is set to "&vol->UNC[2]" in cifs_parse_mount_options(), it should not be kfree()-ed in cleanup_volume_info_contents().
