Hi Marc,

The question is: Why runs the IRQ based transfer into a timeout? The
kernel that produces the crash has ecfbd3cf3b8b ("spi: bcm2835: Enable
shared interrupt support") applied (which was reverted on mainline in a
later patch).
thank for your report. Unfortunately i don't have an answer to your
question, but maybe this is related:

I'll create a patch to fix the NULL pointer deref. As a interrupt based
transfer might run into a timeout for other reasons, too. So better
avoid a kernel crash in that case.
Yes, please
regards,
Marc
