Package: linux-image-5.19.0-10316-gf0f6b614f83d Followup-For: Bug #1025537 OK, I think I have a strong suspect [0]: f0f6b614f83dbae99d283b7b12ab5dd2e04df979 (tags/v6.0-rc1~55^2~2) This is a pretty generic commit, that doesn't seem to touch the nfs stack, but changes something that looks deep enough in the iovec code that it could have an impact. I have solidly re-tested the preceding commit, 310d9d5a5009a93377200b98daa2d84aa2bd8160 (tags/v6.0-rc1~55^2~3), and the Oops doesn't happen there. There is a series of commits that were suggested as part of the `git bisect`, that I wasn't able to build and had to skip. The error was FAILED: load BTF from vmlinux: Invalid argument but no amount of cajoling `pahole` has helped. The merge parent for the series is at 8447d0e75099eb54eea9306c2d43ecfc956d09ed (tags/v6.0-rc1~56^2), which is the preceding merge to the one containing the first bad commit above. I think this is noteworthy as a lot of the commits on this branch are labeled as `remoteproc` which I, as a lay person, think might be related to RPCs. Is there any other tests that I can perform to help diagnose / fix this further?
