Yes, I can confirm this issue on Kali Linux 2019.3, which uses gcc 9.2.1 on kernel 5.2 too (I assume this issue is due to gcc). Removing the packed attribute on lines 81 and 103 in logpkt.c fixes it, but I think Daniel should decide on the correct fix.

Btw, adding aligned(2) attribute along with packed also silences this warning. But I don't think that's the correct fix either. The discussion here explains the issue.
