Could you take a snapshot while you run into a "panic" since even the journal log you post doesn't have the information of the panic. And does it only happen 100% when 2 monitors connected? And it's AMDGPU, could you help verify the latest mainline kernel here? https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.14-rc7/
Please download and install amd64/build generic deb files (files marked A, see section "How do I install an upstream kernel?" in https://wiki.ubuntu.com/Kernel/MainlineBuilds) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1940113 Title: Linux 5.11.0-25 & 5.11.0-27 panic when boot with thunderbolt dock connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1940113/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
