actually, the replacement patch below is better i think - it moves the
ide_lock taking to outside the printing section. That should still be OK
as we dont call other functions from within the section, and it should
also result in slightly more robust printing, as the whole printing code
will be atomic under ide_lock.

Probably fixed, thanks.
