This has been a problem throughout the 2.2 and 2.1 series, but I've only recently been able to confirm that its not just a fluke.
I have an SMC-Ultra EtherEZ ISA adapter, which operates well most of the time. However, after a lot of traffic (maybe a certain amount of data, or a certain period of time), performance becomes abysmal. Connections to anything anywhere stall for minutes at a time, or die out entirely. Transfers, when they work, operate at a 1 or 2 k per second rather than the usual 300k. This is not network performance in general.
If I reset the network stack, by bringing eth0 down and removing the modules (smc-ultra and 8390), then reinsert them, performance returns to normal.
This is on Linux 2.2.13, on an ASUS SMP motherboard, with only one P2-300 processor (kernel is NOT compiled for SMP). I'm including /proc/modules, /proc/interrupts and /proc/ioports just in case.
