This issue is _definitely_ reproducible using the latest current and
my patches on my system. I'm not sure whether or not mount_smbfs and
its shims are MPSAFE...
Snippets of my system info (dmesg + kernel config) is currently
available at the bottom of the email (sorry, I don't have webspace
that I can post to right now).
Thanks,
