Hi @dgatwood, @jazzzz, The test kernels have finished building and are ready for you to try.
Like I said before, they are 5.11.0-44-generic for Focal HWE and Hirsute, and 5.13.0-23-generic for Impish, with just the one commit reverted: commit 5caa90d5fedfcdf57a42c272896cfd0ef6b5c667 commit-upstream: 5255660b208aebfdb71d574f3952cf48392f4306 Author: Jonathan Bell <jonat...@raspberrypi.org> Date: Fri Oct 8 12:25:44 2021 +0300 Subject: xhci: add quirk for host controllers that don't update endpoint DCS Link: https://github.com/torvalds/linux/commit/5255660b208aebfdb71d574f3952cf48392f4306 Let's see if this is the commit which is causing you issues. Could you please install a test kernel and let me know if your USB ports work again? Please note, these test packages are NOT SUPPORTED by Canonical and are for TEST PURPOSES ONLY. ONLY install in a dedicated test environment. Instructions to install: 1) sudo add-apt-repository ppa:mruffell/lp1956849-test 2) sudo apt update For Focal HWE and Hirsute users: 3) sudo apt install linux-image-unsigned-5.11.0-44-generic linux-modules-5.11.0-44-generic linux-modules-extra-5.11.0-44-generic linux-headers-5.11.0-44-generic For Impish users: 3) sudo apt install linux-image-unsigned-5.13.0-23-generic linux-modules-5.13.0-23-generic linux-modules-extra-5.13.0-23-generic linux-headers-5.13.0-23-generic 4) sudo reboot 5) uname -rv Focal: 5.11.0-44-generic #48~20.04.2+TEST1956849v20220112b1-Ubuntu SMP Wed Jan 12 02:26:0 Hirsute: 5.11.0-44-generic #48+TEST1956849v20220112b1-Ubuntu SMP Wed Jan 12 02:31:07 UTC 20 Impish: 5.13.0-23-generic #23+TEST1956849v20220112b1-Ubuntu SMP Wed Jan 12 02:37:08 UTC 20 If you are asked to abort the current kernel removal, say no. You may need to change your grub config to boot the correct kernel. You can follow these instructions to do that: https://paste.ubuntu.com/p/WGpCWTPyTj/ Please make sure the uname is correct on boot. Sometimes newer kernels get pulled in due to metapackage dependencies not liking the linux- image-unsigned package. Let me know if your USB ports start to work again. If they do, we can revert the commit in the Ubuntu kernels, and go and report the issue upstream and get it fixed. If it doesn't, then we will need to do some more tests to try find the commit which introduced the regression.

It disables almost all USB-3.0 and USB-C ports completely. Even though I had automatic software updates turned OFF (or so I thought), my Mac Pro suddenly got a new kernel when I rebooted it this morning: Linux macpro-obs 5.11.0-44-generic #48~20.04.2-Ubuntu SMP Tue Dec 14 15:36:44 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux and it contains a P0 showstopper bug. Upon rebooting, I got dropped into the initrd prompt because Linux could not see the external USB drive that I'm booting from (WDBAGF5000AGY-WESN). I wasted an entire day figuring out what was wrong, and even went so far as to order a replacement SSD, planning to rebuild everything from scratch, because the drive failed to appear in every single USB port I tried. Then I discovered that a different SSD didn't work, either. At that point, I realized that something else was wrong, and I kept trying until I found one other port that worked. I was then able to boot and get dmesg and lsusb output. This kernel update broke not only the built-in ports, but also the ports on a generic USB-C PCIe card (Amazon B08PF8XR73). Mac Pro built-in USB-3.0(A) ports (2x): working Mac Pro built-in USB-C ports (4x): dead USB-C PCIe card USB-C ports (2x): dead USB-C PCIe card USB-3.0(A) ports (5x): dead All devices fail to appear in lsusb when attached to the port, including an Apple USB keyboard, an Anker USB-C Ethernet adapter, a WD SSD, and a Sandisk SSD. I'm going to roll back my kernel to a working kernel, but this package needs to be pulled NOW before it affects too many people. This is too catastrophic a bug to wait even a day.
