Hmmm. S0, S2 and S3 are all on IRQ21 and using high port numbers, but S1 is in the normal spot for a COM2 or second serial port (port 0x2f8, IRQ3). Do you possibly have another device sharing IRQ3 or possibly port 0x2f8? Check /proc/ioports and any files under /proc/irq/3. Also check /var/log/messages and dmesg for any possible information. ---------------------------------------------------------------------- - Rick Stevens, Principal Engineer rstevens@xxxxxxxxxxxx - - CDN Systems, Internap, Inc. http://www.internap.com - - - - Millihelen, adj: The amount of beauty required to launch one ship. - ---------------------------------------------------------------------- -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
