I would like to ask you for more information about the issue. First,
have you managed to collect any error messages during the init phase
where it's supposed to fail?
The thing about that particular commit is it could possibly break
background polling, but I don't see (yet) how it could have damaged the
activation code. Have you tried to reboot a system where any operation
like: pvmove, lvconvert --merge or lvconvert mirror conversion was in
progress in background before you rebooted the system by any chance?
Second step would be to unmute the eventual background processes spawned
during activation. To do it just uncomment
// #define DEBUG_CHILD
in tools/toollib.c:76 lvm2 sources and rebuild.
This should expose all error messages from within the forked off
processes. Also, if you could perhaps give me some hints how to get the
Arch Linux in the same state as when you experienced the issue it would
help us as well.
