According to the manual, the 2416 supports AUTO CMD12.

As I wrote disabling auto cmd12 only works sometimes and other times the irq 
storm happens like with auto cmd12 enabled - always after the first reboot.
So it seems auto cmd12 is not the real reason for the error.

Do you also encounter the second error later on (for me in udev stage):
