        Resolution:
          Severity: enhancement
          Priority: P3

in addition to the badram patch, it would be great if bluesmoke.c (or another 
file in the kernel source) would be enhanced to detect when the machine alerts 
the kernel to an ECC error in ram

after that, the kernel could proceed to free up the memory, make sure it is 
never used again and (maybe) kill the task that was using that memory

it should also print out a message telling the user which address was failing, 
so that we know which address to give to badram on the next boot ...
