I have openSUSE Tubleweed (20191214) with the NVIDIA Drivers for my GTX1060. My CPU is a AMD Ryzen 1700X. I have been experiencing random soft lockups where everything freezes.

I cannot say whether this is because the kernel hung first or the driver did. After that I get some soft lockups in flush_tlb_mm_range and I have to reboot. I have not found a way to reproduce this reliably, it does not look to me that I have to do anything special. Reproducible: Couldn't Reproduce Steps to Reproduce: Normal use. Actual Results: Soft lockup, frozen X. Expected Results: Not crash :) I am attaching my xorg.conf in case it is relevant. Please tell me if there is anything I can do to provide more info. -- You are receiving this mail because: You are on the CC list for the bug.
