Fuck me. I spent so much time trying to get the GPU passthrough setup I didn’t really do basic stuff with the processor, like Gaming.
It all started with me having hard locks when running the Unige Heaven benchmark. 100% of the time it would get to this one spot and my whole computer would hard lock with the display going black. Even in a virtual machine it would go black, and eventually my Linux host would freeze (though not right away, and if music was playing with spotify the music would oddly keep playing).
3dmark would run fine so I thought it was just a weird issue with the Heaven benchmark (dumb assumption I know) but I ignored it. Fast forward to today where I’m playing Grim Dawn and the same thing happens.
I know it’s not my video card, because I’ve had this R9 Fury for almost a year now and never had an issue. I do some gooogling and find instability with original batches of Ryzen (https://www.phoronix.com/scan.php?page=article&item=new-ryzen-fixed&num=1) where Linux users could easily reproduce a segmentation fault compiling GCC over and over again (https://github.com/suaefar/ryzen-test). I run this test and lo and behold it fails within a minute :-/.
The processor has 1726SUS on it, which apparently means it was made the 26th week of this year, so it’s one of the early batches. Sent an email to AMD and hopefully they replace it quiickly without hassle :(
