Public bug reported:
This package needs to be pulled NOW. 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.
