[Bug 111790] [hsw iommu] i915 0000:00:02.0: GPU HANG: ecode 7:0:0x00000000, hang on rcs0

--- Comment #10 from JPT <j-p-t at gmx.net> ---
I checked again and yes, my problem vanishes if I boot
linux-image-4.15.0-1050-oem which is the only 4.x kernel available in Ubuntu
19.10 repo.

With Kernel 4 I get the expected behavior of a swapping system. It lags and is
hard to use in times. But it's not completely locked for several minutes.

Does this proof that it's NOT Freedesktop/xorg related?

How long has the GUI to hang until I should get the above error message in the
syslog?

Hello Alexander

I had a problem with VirtualBox as well. 
My host always crashed because of kswapd running amok after a few minutes of
running the VM. My solution was to add a small swap space (1 GB). Since then
the PC is suffering from the GUI lock mentioned here. 

so, do you have SWAP? What happens with the VM if you remove all swap space of
the host?
did you ever notice kswapd taking 100% cpu?
what do you mean with GPU passthrough? is this VMware specific?

kind regards

Jan
