>Synopsis: Mac Studio hangs; locking problems on WITNESS/MP_LOCKDEBUG kernels
>Category: kernel
>Environment:
System : OpenBSD 7.5
Details : OpenBSD 7.5-current (GENERIC.MP) #69: Wed Jun 12 04:43:28 MDT 2024
[email protected]:/usr/src/sys/arch/arm64/compile/GENERIC.MP
Architecture: OpenBSD.arm64
Machine : arm64
>Description:
System can hang and be unresponsive on a Mac Studio (M2, Ultra),
either soon after boot passes to userland during/after "starting
network", or under load. When on a kernel with MP_LOCKDEBUG and
WITNESS options turned on, these points will trigger locking-related
panics
When trying to bisect and boot onto different kernel binaries built
from different points of time, the system may successfully pass the
"starting network" point at boot without panic'ing, but may instead
panic at some other seemingly random point under load. There appeared
to be no good correlation between commits at different points of time
and the reliability of these locking-related panics happening. (FWIW,
I did not bisect far back enough such that I would need to completely
wipe and downgrade userland.)
See below for ddb session fragments.
>How-To-Repeat:
* Build a recent kernel with MP_LOCKDEBUG and WITNESS options turned on.
* Disable apldrm(4), since display output is currently not working
with this device enabled (separate problem).
* Boot on this new kernel.
* If the system does not panic after "starting network", building a
kernel with `make -j24` will often trigger a similar locking-related
panic instead.
>Fix:
Workarounds:
* use a single-processor kernel;
* non-WITNESS/MP_LOCKDEBUG kernels will obviously not panic, but can still hang
ddb fragments:
1. during "make -j24" (oddly, mach ddbcpu X did not seem to give
information for X > 17 when there are 24 processors)
