[Bug 80419] XCOM: Enemy Unknown Causes lockup

https://bugs.freedesktop.org/show_bug.cgi?id=80419

--- Comment #59 from David Beswick dlbeswick@gmail.com --- Just to update, I've captured three different traces but none have been able to reproduce the problem on replay. I've also tried the following:

* Looping a trace replay over 24 hours continuously -- no repro * Running with a -O0 Mesa build -- hang remains * Going directly to fallback in all cases during si_dma_copy (wild guess based on code comments) -- hang remains

I don't think traces will be a fruitful method of debugging, unless someone can suggest something I'm doing wrong. I'm continuing to look at this. If anyone has a hypothesis and would like to send a patch then I could build and test with it.
