There is more to it. After running 5.0.0-rc6-00153-g5ded5871030e-dirty (with the revert of that patch) successfully for Gentoo update, I upgraded the kernel to 5.0.0-rc7-00011-gb5372fe5dc84-dirty (todays git + revert of this patch) and it broke on rsync again: RepoStorageException: command exited with status -6: rsync -a --link-dest /usr/portage --exclude=/distfiles --exclude=/local --exclude=/lost+found --exclude=/packages --exclude /.tmp-unverified-download-quarantine /usr/portage/ /usr/portage/.tmp-unverified-download-quarantine/ Nothing in dmesg. This means the real root reason is somewhere deeper and reverting this commit just made it less likely to happen. -- Meelis Roos <mroos@...ux.ee>
