To whom it may concern, I am currently running FreeBSD 2.2.5, having decided to give it a try after using linux for about a year now and have run across a problem which despite days (literally) at the screen and an endless search of the net I have not been able to solve. While running ppp I get the following message: "sio2: tty-level buffer overflow", according to the manpage, sio(4), this message is in the application (ie, ppp). I also get this message with my HP2934A serial printer which prints properly so I assume the two serial problems are related. I am running a Cirrus Logic V.34bis modem with a tyan motherboard (1564 dual pentium, 16550A UART's) and this even occurs booting the generic kernel so I assume I missed something fairly trivial during setup. I set the link speed at 115,200 bps in my ppp.conf file and everything loads fairly quickly on my browser, if I set it to 28800 (my modem speed), though, my system slows to a crawl and stty on the port lists 9600 as being the speed With the link speed set at 115,200 bps I will get the overflow and eventually my link will slow to a crawl (after approx. 20-25 minutes). In over a year and a half of running linux and for the last month or so with BSD I have not had any trouble with the operating system and never encountered a problem I could not fix but I am stumped. I contacted Walnut Creek CD-ROM and they thought it might be some sort of hardware problem. Would upgrading to the 2.2.6 kernel fix this? Any input would be greatly appreciated.
