CONFIG_PARPORT_PC_SUPERIO probes for various superio chips by writing byte sequences to a set of different potential I/O ranges. But the probed ranges are not exclusive to parallel ports. Some of our boards just happen to have a watchdog in one of them. Took us almost a week to figure out why some distros reboot without warning after running flawlessly for 3 hours. For exactly 170 = 0xAA minutes, that is ... Fixed by restoring original values after probing. Also fixed too small request_region() in detect_and_report_it87().
