First, a little background info: I've got a P200 running Linux (2.2.18) with an SMC-Ultra (ISA), which is connected to a 10Base-T hub. Initially, I had just this machine plugged into a Notrel 1Mbps modem - no problems. Now, my roomate finally got his own box (Windows ME). I picked up a hub, some cable, and found an old 486 which is now a firewall. Somewhere during this process, I started getting this error message when I'm on the net (thru the firewall): eth0: Tx timed out, cable problem? TSR=0xc0, ISR=0x0, t=[varies] *The windows ME box has no problems connecting...... What I've been doing is stopping and then restarting eth0, which gives me full bandwidth for ~1-5 minutes, after which I end up at about 4k/s. I've replaced the cable (with one I know is good), tried different ports on the hub. I made sure the windows box isn't doing anything stupid (ie grabbing full duplex). I've tried kernels 2.2.14,15,17, and 2.2.18 all with the same results. I haven't been able to get the 2.4.0test series working - I'm guessing that its a pnp problem.... I'm pretty sure the card is still OK - haven't had a problem besides this since I bought it..... Any suggestions would be great....if you need more info, let me know.
