>Description:
	Current panics when running command "mv file1 file2". file1 is
	located on the smbfs filesystem, file2 is on the ffs partition.

	The only usefull information I can provide is a manually rewritten
	ddb backtrace (current 1.6ZJ):

	kernel: page fault trap, code = 0
	Stopped in pid 567.1 (mv) at netbsd: bgetvp +0x16: movl 0x3c(%ecx),%eax

	I initialy found the problem when running current 1.6ZE, for
	current 1.6ZE the backtrace is somehow different:

	kernel: page fault trap, code = 0
	Stopped in pid 1557.1 (mv) at netbsd: bgetvp +0x16: movl 0x3c(%ecx),%eax
	bgetvp(0, c5dfc930, 0, f368e0, f368e0) at netbsd: bgetvp + 0x16

>How-To-Repeat:
	mount smbfs share from somewhere. try to move some file to your
	local fs.
>Fix:
	no idea
