I assume you have CONFIG_PREEMPT enabled? We know it's currently
broken.
It is already disabled:
CONFIG_PREEMPT_NONE=y
# CONFIG_PREEMPT_VOLUNTARY is not set
# CONFIG_PREEMPT is not set
CONFIG_PREEMPT_COUNT=y
I just enabled the new irqstacks...
Ok, the good thing is, that I got today a rp5470 with which I could
reproduce your problems.
The bad thing is:
Beside CONFIG_PREEMPT, CONFIG_DISCONTIGMEM is broken too.
My C8000 runs 3.7.3 happily, so it must have happened after that.
I suspect that you actually have to have discontiguous memory to
trigger the bug.
