Subject: Hang loading omap_rng on MacchiatoBin with 4.15-rc7

Hi,

Loading omap_rng module on McBin causes hangup (in about 9/10 times).
Looking at /proc/interrupts it seems the interrupt starts running like
crazy, and after a while the whole system is unresponsive. This with
Debian kernel (everything possible as modules) and EFI as bootloader.
The EFI firmware appears[1] to use the rng unit to provide a seed for
KASRL, I wonder if the driver needs to depend less on the state left
by firmware, or the firmware needs to de-initialize the RNG before
booting.

I do not have a board with an EFI bootloader, so that may explain why I
didn't managed to reproduce your issue. I really would prefer to make
the driver less depend to the bootloader than the firmware de-initialize
the RNG before booting. However both things could be done independently.

I can have a look on the driver but as I don't have the configuration I
may ask you to test it for me.

My original code had

gMarvellTokenSpaceGuid.PcdEip76TrngBaseAddress|0xF2760000

which means the interrupt storm is being caused by the /other/ RNG,
not the one UEFI uses.

Could you please check whether your UEFI source is still using the
same base address?

Good catch. Looks like it is:
