System freezes during post transaction hooks
This has happened to me now about 6 times now. When updating system through pamac-manager, system hangs during post transaction hooks or installation phase. System never recovers (longest I've waited is 3 minutes) and tty is inaccessible. Initrams is not regenerated, so the rootfs is unbootable and I need to restore system from a pre-transaction snapshot.
This happens frequently but randomly. Usually when it happens pamac-manager window is out of focus and I'm browsing with Firefox or doing some other task. Number of open applications seems to increase the likelihood of a hang. It happens only if I update with pamac-manager, not with pacman.
Manjaro unstable branch, rootfs btrfs, 4gb ram, swap enabled.
