[Bug 1799102] Re: WARNING on boot in Intel GVT-g guest
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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1799102] Re: WARNING on boot in Intel GVT-g guest
Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.19 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
