I have found that a proper reboot is impossible once the card/driver starts 
misbehaving. Anything that tries to do anything with the md device, or any of 
the component drives will hang. Even kernel threads it seems. A reboot or a 
shutdown hangs when it tries to sync the md device, and ALT+SYSRQ+S/U both 
hang. After the first Alt+sysrq+s it will register more of them, but it won't 
print the "Emergency Sync Complete" message.
