Thanks for report. I just released v5.4.22-rt13 including this patch: https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git/patch/?id=b901491e7b9b7a676818d84e482b69be72fc142f which should fix the problem. Since I'm not able to test it myself, please let me know if anything else pop up. Sebastian

I am testing v5.4.22-rt12 now. However, it seems there is a new error related to vmwgfx. When it happens, the graphics hangs forever. I am sorry for the long message. I couldn't tell which part of the dmesg message is useful this time so I post all messages since the first error. The full dmesg message is attached as dmesg_demp_03072020.log Could you please take a look when it's convenient to you?
