Comment 2 Michal Sekletar 2015-11-16 12:23:48 UTC
This is probably the unaligned access issue in systemd's siphash24 implementation. Upstream bug, https://github.com/systemd/systemd/pull/1911.

Comment 7 Marcin Juszkiewicz 2015-11-19 12:56:52 UTC
Built 226-3 with current toolchain and it works.

Installed 228-2 on top of it and systemd crashed in a way that even reboot is impossible without going back to 226-3 ;(

Definitely possible. See #1271387.
