Description

Not sure what triggers this, the machine was under a heavy load (adding music metadata to mysql, downloading with rtorrent, playing music).
Here are the pictures (panic and trace) with the tar'd kernel dump:

TIA for looking into the issue.

No, this one was due to SMBFS's VOP_LOOKUP function not setting the
returned vp to NULL when returning an error. I'll get it fixed.

Fixed. It was a sanity check assertion in the kernel code. SMBFS
was returning a non-NULL vnode on error.

Thanks. I can't confirm, since I don't know how to reproduce, but I believe you. :-P

I was hoping this would also fix my mount_smbfs panic but, sorry to

Is there a crash dump or backtrace available?
