Any more thoughts on this please?

Now Ports collection support for 10.3 has ended, this bug is now a hard blocker
preventing me from upgrading to 10.4 and continuing to apply security fixes.

I once had a box where sysctl -a would hang, too. It's been a while, so no more
details until I stumble open that box again.

I'm out of ideas.

Could you please test 11.1-RELEASE or 11.2-PRERELEASE? I've seen similar
reports that were 'fixed' by upgrading to 11.1.

Well, there is the sx owner which blocks snmpd.  It does not make your note
about the request length less valid, but still first thing to look at is the
state of the lock owner.

Print p *(struct thread *)0xf80079fd3000, then get the backtrace for that
thread.

How does one recover original sysctl name? This one seems to be ACPI-related,
see attachment.

Mark, you should check if you have BIOS update for this box.

Thanks. BIOS is 1006 (updated before I filed this bug) from
https://www.asus.com/uk/Motherboards/PRIME-H270M-PLUS/HelpDesk_Download/. I see
there's now a 1010 I could try. To reiterate this is fine under 10.3.

The process holding sx lock is hald:

257 Thread 100247 (PID=1343: hald)  sched_switch (td=0xf80079fd3000,
newtd=, flags=)
at /usr/src/sys/kern/sched_ule.c:1956

Hald is installed with ports/sysutils/hal.

Mark, why do you need hald? If it's possible, try running 10.4 with hald
disabled.

Ah, thank you!!

I don't recall why hald was installed (it was probably from a long time ago).
I've removed it, and so far, I'm not seeing any symptoms, so long as I avoid
sysctl -a.

:)
