Hi Daniel,

re comment #98: That's to be expected. The problem was with *recording* the
trace, not with playing it back. A trace recorded without the patch will crash
when played back, whether the playback session has the patch or not.

re comment #99: Interesting, and yes, I'd say that's a HUD bug. Could you
please file a separate bug report for that?

Those metrics are very unlikely to help, though. One of my crash reproductions
had a VM fault where a page that should have been there (according to the
radeonsi VM fault dump) apparently wasn't. There are some theories (like
problems with the sdma ring that is used to update the page table entries), so
it's likely some race condition is involved.
