Network problem

Hi,

Once a while, my system got the error message "eth0: Tx request while
isr active". It keeps displaying on the screen and effectively hangs my
system.

I have to reboot the computer to clear this error.

Any information on this error will be appreciated.

Thanks,

Hi,
I have a networking problem which I have not managed to solve after
reading the relevant HOTWO files. Any help will be appreciated.

Setup:
Intel Pentium Pro with 3Com 595 100Tx card connected to 100T network.

The machine has WIN/NT installed and manages to access the network.

Software:
- I have installed Slackware 3.1 (from InfoMagic CDROM)
- run "netconfig" with appropriate parameters (double checked)

Symptoms:

- Kernel recognizes right device
- No error messages at boot time

- ifconfig shows the device setup, but shows 0 on all TX and RX counts,
including errors counts.
- same for /proc/net/dev

- routing table seems ok (as far as I understand these things)

Yet, I can't run a single network application.

ping to my gateway just hang. When I press ^c, it reports "NN packets sent, 100% packet loss".

I tried to ping the machine from another machine, and again no
communications.

The interesting thing is that "ifconfig" keeps insisting that nothing was sent
nor transmitted.

The only thing that I can think of is that the device parameters are not set
right. In particular "ifconfig" reports:

eth0 Link encap: 10MBps Ethernet ...

when the net should 100MBps.

Can this be the problem? If so, how do I set the right mode for the device?

Thanks,

-Nir
