Interesting to me as well. I also have such a similar
problem. But I wanna to know how I can return to 
u-boot with software workaround after kernel hanging.
At least, I must power-off and power-on my target to
get back to u-boot console. If so, the last kernel 
printk message would lost IMHO.

Thanks,

Sam
