I can't find suspicious code in r282213 which could cause this strange regression, but I verified carefully that problem arises with r284665. Actually, r282901 (https://svnweb.freebsd.org/base?view=3Drevision&sortby=3Ddate&revision=3D= 282901) is the real trigger, verified by putting nooptions RACCT nooptions RACCT_DEFAULT_TO_DISABLED nooptions RCTL into my kernel config -> problem vanishes! Setting "kern.racct.enable=3D1" doesn't make any difference, as soon as 'kern.features.racct' exists, there's the ahci(4)/ahcich2 timeout and machine doesn't finish booting. Unfortunately, I don't have any idea how to track this down to the actual culprit, but I hope the RACCT hackers do have ;-) Shall I open a bugzilla ticket?
