On the odd chance, I did this: [root@coyote dev]# lsof | grep ttyS [root@coyote dev]# so nothing has them tied up. Then a setserial /dev/ttyS0: [root@coyote dev]# setserial /dev/ttyS0 Cannot get serial info: Invalid argument And [root@coyote dev]# setserial /dev/ttyS1 /dev/ttyS1: No such device or address But as you can see, it does exist, the cm11a is still plugged into it etc etc. I am beginning to think we have a buglet in this kernel. Since I'm running the latest 2.6.19-rc5 on the FC2 install on the /dev/hdb drive, I'll copy that vmlinuz and initrd to this boot partition, and edit the grub.conf to use it for my next test sometime today. If it then works, I'll bugzilla it. Thanks. -- Cheers, Gene -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
