Public bug reported: I'm getting annoying crashes of CIFS while removing files from a mounted share.
There appears to be a fix for something that sounds likely to fix it in 2.6.26 with commit 77c57ec89682c73785d12d51a6d1f873b292fa42. Search for "[CIFS] don't explicitly do a FindClose on rewind when directory search has ended" in the below file: http://www.kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.26-rc3-git4.log Ubuntu
