This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1919275

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

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.

Apologies for not getting back to this earlier, it looks like the verification was already done.

We're still waiting on verification for Groovy - the kernel task was verified, but the groovy build of crash has not been verified yet.

The arm64 build failure on groovy is due to a commit missning regarding gdb. See bug https://bugs.launchpad.net/ubuntu/+source/crash/+bug/1931435.

On riscv64 it seems it never built successfully and the failure is irrelevant to the patch.
See bug https://bugs.launchpad.net/ubuntu/+source/crash/+bug/1931432.
