So, I have been running the patched kernel for quiet a while now, and it works fine for me, but last night I did hit a surprising issue - the Linux emulator does not work on Ryzen / Epyc. I tried this on two machines (both with the patches) and it coredumps when simply running bash on both of them. I copied the OS over to an Intel machine, and that works fine.

I have not tried running with an unpatched kernel on the Ryzen machine (I dont have one to hand) but I did try applying the sysctls to the Intel box to see if that wuld cause the Linux binaries to crash. It didn't.

-pete.
