I have noticed one more consequence of this bug, which can be very painful for those who are running thier own servers. Regardless that it is possible to connect by SSH and operate server normally, in my case when I was trying to reboot it whole power down procedure is carried properly up to closing of journal, but server freezes at the end and is not restarting, so if one is far away from infrastructure, can be in trouble. Fix with nomodeset is solving this restart issue.
My server is on Ryzen 3 + Radeon Vega integrated GPU. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2068738 Title: AMD GPUs fail with null pointer dereference when IOMMU enabled, leading to black screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2068738/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
