I've noticed on systems with AST/4 port and Digi PC/4/8 cards that when a soft-reboot occurs (i.e. after crash/panic), the SIO ports are not all initialized properly, whereas after a shutdown -r or reboot, or cold boot the ports all init properly. I've looked at the sioprobe function in the sio.c module and there appears to be lots of instances where the programmer added EXTRA_DELAY? Has anyone else seen this problem? Appart from forcing the machine to reboot if all the sio ports are not detected, is there a clean way to make sioprobe find all the ports after a crash? ----------------------------------------------------------------------- Andrew Webster Network Manager / Special Projects Dataradio Inc. 200-5500 Royalmount Ave. TEL: +1 514 737 0020 Town of Mount Royal, QC, CANADA H4P 1H7 FAX: +1 514 737 7883 http://www.dataradio.com Email: awebster@dataradio.com
