We run a in-house dialup server off a BOCA 16 port board (BB2016). When we started there were only 8 modems on the board, but as we have expanded and as they are all used the board continues to freeze up all of the serial ports off the board. The only way to un-freeze is to shutoff all getty's on the serial ports, give it a few and turn them back on (via /etc/ttys). The kernel has been patched in sio.c to set ftl_init to 8 instead of 14, and we seem to have fewer overflows, but they still occur, and when they do the entire board freezes. With our increased usage it is to the point now that there are one to two freezes a day. We need to find a solution, any suggestions? BOCA did tell us the UART on the card is fast enough to handle what we are doing, so I dont suspect that as a problem. The machine is a 486DX2 on an ISA/EISA MB with 20MB RAM. It is not used for much else, and is running 2.1.0 (when I attempted to upgrade to 2.1.5 the kernel paniced after probing all of the devices, on the SCSI card--which, oddly enough, identified differently than it does is 2.1.0--it is an Adaptec 2740A/42A/40AT/42AT). Enjoy;
