You are welcome, but this means, stable is not currently buildable on 
i386 -- a Tier1-platform... Is not that monitored for? On the ports side 
of things, I'd be getting an automated build-failure notice shortly 
after making a change, that breaks a build...


I applied the diff you linked to by hand and the kernel-build moved on, 
thank you! Yours,

[Bug 213903] Kernel crashes from turnstile_broadcast (/usr/src/sys/kern/subr_turnstile.c:837)

--- Comment #55 from Mark Millard  ---
(In reply to muxx.dev from comment #54)\

Looks  to me like ts==0x0 was the starting value
given to turnstile_broadcast in each backtrace
listed in this buzilla bug (213903), for example:

(kgdb) list *0x80b3a89c
0x80b3a89c is in turnstile_broadcast
(/usr/src/sys/kern/subr_turnstile.c:837).
832
833 /*
834  * Transfer the blocked list to the pending list.
835  */
836 mtx_lock_spin(_contested_lock);
837 TAILQ_CONCAT(>ts_pending, >ts_blocked[queue],
td_lockq);
838 mtx_unlock_spin(_contested_lock);
839
840 /*
841  * Give a turnstile to each thread.  The last thread gets
Current language:  auto; currently minimal
(kgdb) backtrace
. . .
#8  0x80b3a89c in turnstile_broadcast (ts=0x0, queue=1) at
/usr/src/sys/kern/subr_turnstile.c:837
#9  0x80ad48cf in __rw_wunlock_hard (c=0xf800437de858, tid=, file=, line=) at
/usr/src/sys/kern/kern_rwlock.c:1027
. . .

Note that ts==0x0 would be a problem for:

TAILQ_CONCAT(>ts_pending, >ts_blocked[queue], td_lockq);

So I wonder if __rw_wunlock_hard is providing a bad ts
value. If yes: the problem then occurs before the
turnstile_broadcast call is made.

errors from port make (analyzed: bug in pkg)

[Peter]

For a long time already, I get these strange messages whenever building 
a port:


pkg: Bad argument on pkg_set 2143284626

Today I looked into it, and found it is easily reproducible:

# pkg audit whatever
pkg: Bad argument on pkg_set 2143284618
0 problem(s) in the installed packages found.
#

Looking closer, I found this offending call in src/audit.c:exec_audit():

pkg_set(pkg, PKG_UNIQUEID, name);

This goes into libpkg/pkg.c:pkg_vset(), but there nobody is interested 
in an UNIQUEID parameter, so that the parameter does not get fetched 
from the va_list.


It does not do any harm, but it is ugly.
Please fix.

Error in /usr/src/release/release.sh

[Bryce Edwards]

When trying to build a set of RELENG/11.1 release files, I'm getting the
following error (tail end of output) in the release.sh run:
--
>>> Kernel build for ALLWINNER completed on Fri Aug 11 22:24:02 UTC 2017
--
make -C /usr/src/release  obj

*** Error code 1

Stop.
make: stopped in /usr/src/release

Here's the contents of my release.conf:
CHROOTDIR="/usr/local/build/chroot"
SRCBRANCH="base/releng/11.1"

TARGET="arm"
TARGET_ARCH="armv6"
KERNEL="ALLWINNER"

NOSRC=yes
NODOC=yes
NOPORTS=yes

And the contents of the R/ directory after the run:
bryce@tahiti /usr/local/build $find chroot/R/
chroot/R/
chroot/R/ftp
chroot/R/ftp/kernel-dbg.txz
chroot/R/ftp/tests.txz
chroot/R/ftp/doc.txz

chroot/R/ftp/MANIFEST
chroot/R/ftp/kernel.txz
chroot/R/ftp/base-dbg.txz
chroot/R/CHECKSUM.SHA512

Thanks in advance for any insight.  I'm not having luck with make
distributeworld in /usr/src either - The use of DESTDIR & DISTDIR in the
Makefiles seem to alternate between absolute & relative use of those and it
isn't cooperating with me (which is why I was trying to just go with
/usr/src/release/release.sh)

How many snapshots do you have ? I have only seen this behavior with LOTS (not 
hundreds, but thousands) of snapshots.

What does your `iostat -x 1` look like ? I expect that you are probably 
saturating your drives with random I/O.
