Sorry, the joy was (relatively) short-lived: Even with `/etc/default/grub` `GRUB_CMDLINE_LINUX_DEFAULT` setting set to empty, I can still reproduce this problem with the lp1766076 kernel: it definitely happens less - maybe 1 in 3 times instead of almost always - but it still happens.
Here's a boot dmesg log of a failing boot with no (additional) kernel command line flags - xhci_hcd assumes the controller died on timestamp 27, after which none of the USB things on the dock work. ** Attachment added: "lp1766076-boot-dmesg.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1856161/+attachment/5314569/+files/lp1766076-boot-dmesg.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1856161 Title: Thunderbolt dock fails to connect USB devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1856161/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
