During the mount the vnode is flagged as S_UNMOUNTING. Then when the file system is mounted a second time the kernel hangs, possibly waiting for the old vnode to disappear. The attached patch fixes the problem, >How-To-Repeat: >Fix: For some reason I'm getting the following error when trying to attach the patch file with firefox. There is an error with your problem report submission. The problem was: Patch file has wrong content type: got application/octet-stream but was expecting one matching text/.* or application/shar. I also sent it to freebsd-fs, message-id is <20070717183651.GA16599@delft.aura.cs.cmu.edu> >Release-Note: >Audit-Trail: >Unformatted:
