Hi Grzegorz, Thanks for taking the time to submit a bug report and helping to improve Ubuntu.
Your bug report mentions that you aren't able to test unsigned kernels, but doing so would greatly help to identify if this problem has been resolved in upstream Linux. If you can work around this limitation, please follow this Ubuntu Wiki article and try the latest mainline build: https://wiki.ubuntu.com/Kernel/MainlineBuilds. Alternatively, if you can identify which prior kernel version did not have this issue, we can narrow down when this issue was introduced. ** Changed in: linux-oem-6.17 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2159662 Title: xHCI: USB device tree behind a USB-C/Thunderbolt-tunneled hub repeatedly disconnects/re-enumerates (error -71) on ThinkPad P14s Gen 6; stable on native PCH xHCI (USB-A) and under Windows To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-oem-6.17/+bug/2159662/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
