Hi,
we have a custom board based on beaglebone black device. Sometimes it happens during the boot that the pm33xx module is not properly loaded with the following trace:
[ 3.479401] pm33xx pm33xx: PM: Unable to allocate memory from ocmcram
[ 3.485923] pm33xx: probe of pm33xx failed with error -12
Any idea what can be the reason or what I can investigate?
Unfortunately I am not able to reproduce reliably as it happens very rarely and randomly.
Linux kernel: mainline 4.19.68
Thanks.
