vmw_fence_wait() at netbsd:vmw_fence_wait+0xdc

Just to confirm, what does `info line *(vmw_fence_wait+0xdc)' say in
gdb?

And, if you can get to the frame in gdb, what does gdb say &cb.wq is
in the vmw_fence_wait frame, and what cv is in the cv_destroy frame?

Let's confirm it is the cv you think it is -- I suspect it might be a
different one.

Since I no longer have the exact kernel that crashed, I tried to reproduce the issue with the latest one I have (with my workaround backed out). But it seems like the panic doesn't occur anymore. I'll give you the info the next time it panics.
