After updating my PogoPlug 4 system I'm getting an error about coherent_pool size when the system try to load a firmware of dvb-t usb device.
linux-kirkwood & linux-headers-kirkwood: updated from 3.9.6-1 to 3.11.1-2
linux-firmware: updated from 20130610-1 to 20130917-1
I guess I'll need to set this manually in the uboot, any recommended value for the size of coherent_pool ?
