This sounds like a number of bugs we have run into. Perhaps moving the serial card to being a PUC device like with did with the Smartlink modem in the PR below http://www.freebsd.org/cgi/query-pr.cgi?pr=3Dkern/74786 Also, if you do ever use the USB bus, there are a number of bug fixes you will need, especially with uhid. > >Anyone have any ideas on how I can get this to work? Should I try = FreeBSD=20 >5.x? If its the problem we are running into, no it will still be there under RELENG_5. However, in general RELENG_5 is much more stable, especially if you cannot turn off USB in the BIOS. ---Mike -------------------------------------------------------- Mike Tancsa, Sentex communications http://www.sentex.net Providing Internet Access since 1994 mike@sentex.net, (http://www.tancsa.com)
