NetBSD 10.99.10 (APACHE) #1: Fri Oct 13 06:52:46 CEST 2023
Architecture: aarch64
Machine: evbarm
>Description:
	After upgrading my -current aarch64 machine (nanopi m4v2) to
	actual kernel and userland the old (and newly compiled)
	pkgsrc/mail/dovecot2 fails:

	master: Dovecot v2.3.21 (47349e2482) starting up for imap, pop3, lmtp
	log(1389): Panic: kevent(EV_ADD, READ, 6) failed: Invalid argument
	master: Error: service(log): child 1389 killed with signal 6 (core not dumped - https://dovecot.org/bugreport.html#coredumps - set service log { drop_priv_before_exec=yes })
	master: Error: service(log): command startup failed, throttling for 2.000 secs
	master: Error: service(config): command startup failed, throttling for 2.000 secs
	master: Error: service(anvil): command startup failed, throttling for 2.000 secs
	master: Error: service(config): command startup failed, throttling for 4.000 secs
	master: Error: service(stats): command startup failed, throttling for 2.000 secs
	master: Error: service(config): command startup failed, throttling for 8.000 secs
	master: Error: service(pop3-login): command startup failed, throttling for 2.000 secs
	...
>How-To-Repeat:
	Try to run pkgsrc/mail/dovecot2 on an actual souce based
	aarch64 evbarm machine and see it fail.
>Fix:
	Reverting to a kernel based on sources (before):

	NetBSD cochise 10.99.10 NetBSD 10.99.10 (APACHE) #1: Fri Oct 13 06:52:46 CEST 2023

	runs dovecot2 fine.
