Hi!
This was greeting me overnight... I don't yet know how reproducible it
is, it happened once so far.
Best regards,
Pavel

Please pipe the stacktrace into ./scripts/decode_stacktrace.sh
to get a readable stacktrace, otherwise this is pretty much useless.
FWIW the only SPI device in the Droid 4 is the PMIC.

I've seen this too, and looks like reverting commit c9ba7a16d0f1
("spi: Release spi_res after finalizing message") fixes it based
several days of testing.
Noralf and Mark, any ideas what needs to be fixed here?
Below is the stacktrace I see without c9ba7a16d0f1 reverted,
not sure how to reproduce but it seems to happen within about
one to two days of uptime.
Regards,
Tony

Mark has a revert in his for-5.2 branch:
spi: Fix Raspberry Pi breakage
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git/commit/?h=for-5.2&id=0ed56252c9567351344cb7b5cff6140e1bcec943
I don't know when or if he has sent a pull request.
Sorry about the breakage.
