What causes this WARNING is the host kernel. Using latest drm-tip (d63c50f2b014037b43c1c0f108c61e0a31ede3c1) in the host, there is no WARNING in the guest, while the WARNING happens when the host uses 4.18.0-12 (HWE 18.04 Edge). 4.15.0-42 does not support iGVT-g with dma-buf, so it's not useful to test.
It seems the results weren't dependent of the Linux kernel version on the guest: they were the same with 4.18.0-11, 4.18.0-12 and 4.19.5. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1799102 Title: WARNING on boot in Intel GVT-g guest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1799102/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
