Well trace points should work. They use a ring buffer and are specially 
made to work in such situations.

Alternative would be to audit the udev code and allow giving a GFP mask 
to the function to make sure that we don't run into the deadlock.

Another alternative is a debugfs file which just blocks for the next 
reset to happen.
