System: NetBSD valkyrie 7.99.42 NetBSD 7.99.42 (VALKYRIE) #20: Fri Nov 25 18:33:19 EST 2016  dholland@valkyrie:/usr/src/sys/arch/amd64/compile/VALKYRIE amd64
Architecture: x86_64
Machine: amd64
>Description:

With the latest radeondrmkms and native X, and my particular hardware,
the following failures occur:
   - start supertuxkart and exit immediately -> the X server dumps core
   - start supertuxkart and start a race -> the X server wedges solid

more data to follow as time permits.

This does not happen on another machine I have with the exact same
radeon but an older kernel and xsrc (7.99.30 from June) ... and
fewer/slower CPUs. I am going to be updating it next week and can test
supertuxkart there too.

>How-To-Repeat:
>Fix:

dunno.
