Patch request submitted:

changing status to 'In Progress'.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the 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-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

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!

Though this is not at all clear, this focal verification request is for focal:linux-oem-5.13.

[Frank Heimes (fheimes)]

Ok, since there is no linux-oem-5.13 for s390x, I'm setting the tags to "verification done on focal", to unblock this ticket. (Thx for the clarification apw.)

Nice try ... but I have nothing to verify. I'd at least need a git to clone from and build my own kernel or a kernel package or whatever to verify this.
Btw. I also do not have any 21.10 ubuntu but I think a 21.04 would work also.

downloaded and installed the kernel packages. Here is the uname output:

uname -a
Linux t8314009.lnxne.boe 5.13.0-14-generic #14~lp1933496-Ubuntu SMP Mon Aug 16 10:53:26 UTC 2021 s390x s390x s390x GNU/Linux

Verified with some hand-triggered tests that the feature is there and works as expected. All good.
