This bug is awaiting verification that the linux- hwe-5.11/5.11.0-40.44~20.04.1 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.

[Test Plan] * Check the built kernel's config that it has CONFIG_DEBUG_INFO_BTF=y * Check build log that it contains ``` BTF .btf.vmlinux.bin.o ``` [Where problems could occur] * In the future, kernel may require even newer version of pahole from dwarves, making the builds fail to build again, as building BTF debug information will now be required. Until either BTF is disabled again or pahole is upgraded again. [Other Info] * Latest pahole is available from focal-proposed, hirsute-proposed, impish release, builders-extra PPA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1945632/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
