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.
