Did you reboot after upgrading to 2.6.15-4? That upgrade happened for me
this morning, and the upgrade warned that I would need to reboot, so I did.

Also, I noticed a problem with shfs on AMD64 with a 2.6.14 kernel last
week or the week before, whereby normal everyday commands like ls
started segfaulting. It might be a related problem -- I didn't take the
time to debug it.


I usually have a GPG digital signature included as an attachment.
See http://www.gnupg.org/ for info about these digital signatures.
