tmpfs is still hosed but now the kernel drops into ddb and the longjmp 
botch panic is gone.
Instead it borks here:
trap type 0x7: pc=0xf0060274 npc=0xf0060278 psr=48001c3<S,PS>
kernel: alignment fault trap
stopped in pid 41.1 (cp) at netbsd:tmpfs_vptofh+0x14:
std %g2, [%o1 + 8]
db> bt
tmpfs_vptofh(0x2d, 0xf44d5be4, 0xf3a20478, 0xf3a2c3b8, 0x0, 0xf3a2ee70) 
at netbsd:nqsrv_getlease+0x288

this happened when I tried to copy a file into a mounted tmpfs.

have fun
Michael
