 Hello,

 For sometime now we've used a backend (non-internet accessible) server
 to
 generate static content that is shared via NFS to a front-end server for
 internet access. Both machines use ZFS exclusively.

 The webserver is nginx and we had AIO set to on, with the AIO module
 built
 into the kernel.In 10.x it "just worked".

 About two weeks ago I upgraded that backend machine to 11-STABLE in
 order to
 start building packages for 11. I've just updated it again to r305417. I
 don't recall it not working as expected.

 More recently I upgraded the front-end machine to 11-STABLE @r305311.
 Since
 then, AIO is not working and I get a critical error in the nginx logs
 like
 this:

 2016/09/05 15:58:02 [crit] 21145#0: *649 aio_read("/path/to/file")
 failed
 (45: Operation not supported) while sending response to client ...

 In 11 AIO is built into the kernel by default, and I have confirmed
 that it
 works as expected in files from a local file system. Since the webserver
 isn't aware that the file system in question is shared via NFS, it seems
 this is an operating system issue.

Mmm, etcupdate should not remove a modified file.  However, etcupdate
assumes that a file removed from /etc is supposed to be removed.  If
your libmap32.conf is unmodified then it truly is pointless since
/usr/lib32/private doesn't exist anymore in 11.

Significant for what ?  First message mostly repeat the setting in the
BIOS which you frobbed.  The second message indicates that xAPIC
timings for ICR reads were calibrated, i.e. x2APIC mode was indeed
disabled.

Is this significant? On carsh case present 'x2APIC available but
disabled by DMAR table' and 'LAPIC: ipi_wait() us multiplier 1 (r
116268019 tsc 2200043851)'

On successful boot both messages absent:
