Note: This isn't a bug-report per-say, more a thread looking for potential fixes.
I've been struggling with this for a while and any 'solutions' I've found on the forums thus far have not been successful.
Background:
I've been passing through an RX480 without a dongle (i.e. with VNC enabled) absolutely fine for months (up-time of 40+ days at one point), however now as I want to use it as a remote Windows workstation I've tweaked it to make Parsec work properly (4K HDMI Dongle + Parsec).
However in that configuration it totally locks up the machine with zero information displayed in the log or on the IPMI KVM view screen (Its a total and immediate lockup... which is useful).
In addition any attempt to close a Remote Desktop session also results in the machine totally locking up, a reboot is the only solution. The notes for changing the WDDM thing hasn't made a difference (in any case an update KB is installed that allegedly fixes it).
I have the AMD reset plugin installed and I'm running 6.10-rc2 and rc1 prior to that.
Two cores + HT isolated (2,3, 6, 7) assigned to the VM, along with 6144MB RAM.
Q35-6.1 (i440fx never seems to work for me, gets stuck at the boot screen or Windows stops responding)
OVFM TPM
USB Controller (3 qemu XHCI)
Windows 10 21H2 - totally 100% up-to-date, latest AMD drivers, latest VirtIO drivers, etc...
I've now taken the dongle out and added the VNC server back in and I'll test across the next two weeks (Parsec also disabled).
Does anyone have any thoughts on what is causing UnRAID (or Windows to cause UnRAID) to completely lock up either by closing a Remote Desktop connection or randomly at some point in time when there is no VNC enabled?
If it wasn't for the fact GPU prices are insane at the moment I'd pick something up newer, but alas we are where we are.
I'll post the diagnostics plus information on other server configs when I have more time, but for now if anyone has any ideas, please feel free to let me know and I'll try them!
