Keir, Jan, et al: Can you take a look at this patch to see if you think this is the right way to solve this problem? This particular patch is still being tested by the partner who saw the problem; but a less safe change -- just returning "OK" if the pci device didn't exist -- did solve the problem. It seemed like this check was probably there for a reason, so I wanted to keep it in place. (Although the c/s in which this check was introduced, 18906:2941b1a9, only mentioned locking changes, not introduction of new checks.) Thanks, -George
