It does look like it.  I knew I'd seen that telltale "stge" in a cpu
backtrace somewhere, just didn't remember where.

I'll append my system data, etc. to PR 54217 and request 54253 be closed
as a duplicate.

The machine has a fairly recent Linux Mint on the local disk and that
works fine.  I only netboot it (and sometimes boot a live USB image) to
test any changes/updates to "nouveau".  As such, it only ever boots
-current.

I do have a netbsd-8 live USB image I could boot before trying any boot
of -current.

I haven't tried all the combinations yet.  Most recently, I booted it
to check the display resolution, so I immedately disabled "atabus" in
userconf so it would boot with "nouveau" active.  Then I was keen to
capture the panic, so rebooted and disabled "nouveau" in userconf.
It didn't panic.

I rebooted again without changing anything and it panicked (with black
screen during "nouveau" activation).  Somehow I did manage to get it
booted with both "nouveau" and "atabus" active, but I haven't made
thorough notes to see if there's a pattern other than its more likely
after power-on.
