This bug is awaiting verification that the linux-raspi/5.13.0-1010.11
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-impish' to 'verification-done-impish'. If the
problem still exists, change the tag 'verification-needed-impish' to
'verification-failed-impish'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!
