With kernel mainline 5.5.1, it does get a little bit further, only BAR 14 and 0 fail to assign on the second try. See attached dmesg. But symptoms are still identical: no peripherals work except for video.
Any way I can systematically search for a workaround using pci= kernel parameters? ** Attachment added: "kernel_mainline_5.5.1_notworking_dmesg_dock_plugged_after_boot.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1860284/+attachment/5325261/+files/kernel_mainline_5.5.1_notworking_dmesg_dock_plugged_after_boot.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1860284 Title: thinkpad thunderbolt 3 dock gen2 with pci memory allocation errors on Yoga C940 unless plugged in before boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1860284/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
