Hi,
I am having a bit of a problem here with my ethernet setup. I have two
cards in this machine, a 100basetx 3com 3c905b and a 10baset 3com isa 3c509.
The LAN is 100basetx and the 10baset goes out to the internet. The machine
is behaving as a bridge.
There is also a modem in the machine and it seems that when the modem is
receiving data as well as the 10baset network card, serial input overruns
will occur. The modem even locks up hard on occasion. I tried setting
CONFIG_CPU_IS_SLOW and CONFIG_HW_FLOWCONTROL to no avail.
I'm thinking it's because it doesn't get a chance to handle the serial
interrupts with so many ethernet interrupts coming in and it only being a
Pentium 75 and all. I put the modem on irq 9 and the ethernet cards on 11
and 12 so the modem should have higher priority, still no luck.
Would upgrading to a PCI card even an ne2k card solve the problem. That way
it'll be on a 32bit bus. Can the ne2k IRQ handler get in and out faster
than the 3c509 one?
Many thanks,
Shane
