Betreff: Re: [vfio-users] GPU HDMI audio passthrough weird behavior?
My dmesg log for spammed with the msr errors. That is the reason i enabled it. Since i am on the road i was not able to copy my grub cmdline to kernel, so i copied those lines below from the net.‎ I know i have the ignore msrs and one of the allow unsafe intwrupts line in it. But not which one. Since one is trying to get the card working i figured one will prob. Test them seperate if not working...
My gpu was not working without, so i guess the answer is both a little.

Were you explicitly told in dmesg to allow unsafe interrupts, or you've just enabled this option twice because you found it somewhere on the net?
