Hi Tilman,
The fix for this bug report was already released in the past and marked
as "Fix Released". In this case the regression is handled by a new bug
report and we usually keep the original one without duplicating it.

Good to know. Thanks for the information. I guess I should subscribe to
that other bug then. Would it be an option to mark this one a duplicate
of the new one?

Sorry, I can't help with that.
All machines on which I have seen the issue so far are production machines
under configuration control where I cannot install an experimental kernel.

Is it possible to test on a machine that is not in a secureboot default
environment that experienced these issues? i.e. a non-core device. This
would be to just confirm if the fix does anything.
If so I put up the kernel .deb files with the possible fix here

The log I attached in comment #15 is from a cold boot, but I'm seeing all four
combinations of outcomes:
cold boot -> failing
cold boot -> working
warm boot -> failing
warm boot -> working
on ~40 Focal servers with identical hardware.

Hello Dries and Tilman,
Thank you for providing the logs and other relevant information. For
clarification, when you were testing if the issue still exists, was this
from cold boot or warm boot?
And if you sometimes see it working from cold boot it indeed seems to be very
racey. There now should
See the attached dmesg output. Here's the relevant line:
[ 37.400119] usb usb1-port4: couldn't allocate usb_device
The lspci utility is not available on Ubuntu Core 20, but when I boot
Ubuntu Desktop 20.04 LTS from a live USB drive it yields the following
output on the affected machine:
$ lspc
a-schmidt@ulanbator:/var/log$ lspci -nn | grep USB
00:14.0 USB controller [0c03]: Intel Corporation C620 Series Chipset Family USB
3.0 xHCI Controller [8086:a1af] (rev 09)
Output of dmesg is attached.
At kernel timestamp 2.544086 you can see the telltale "couldn't allocate
usb_device" message.

Hi, would it be possible to provide the dmesg output after boot?
Could you also provide the output of 'lspci -nn | grep USB' since since a lot
of these issues seem to be USB card specific and I am unfamiliar with your
hardware.
As Jarkko mentioned, in 5.4.0-90 there were some patches that were
Confirmed, this seems to be broken again on Ubuntu Core 20 devices using
the latest pc-kernel Snap on the 20/stable channel (5.4.0-104.118.1).

Broken again on Ubuntu 20.04LTS after updating to kernel 5.4.0-105-generic.
USB2 devices not detected on USB3 ports after reboot, but appearing after:

This got broken again in 5.4.0-90 (Ubuntu 20.04). USB2 ports work but USB-C
don't. Reattaching USB plug doesn't help, but after suspending and resuming USB
starts working again, until the next time I restart the computer. The reason
seems to be that the temporary fix was reverted:
