Hello,

the only hint I could find is from the amr(4) man page:

  amr%d: bad slot %d completed

  The controller reported completion of a command that the driver did not
  issue.  This may result in data corruption, and suggests a hardware or
  firmware problem with the system or controller.

Do you have a second controller available to test? We have the same
controllers in several of our servers and I would interested to find
out what is the problem just in case..
