Any idea why eth0 timed out (TX hung) when using SIMULTANEOUSLY 10 Mbit ethernet and modem-emulated ISDN with a ipmasq (ipchains) setup?

Problems also occur with extensive pinging home lan meanwhile connected to ISP via PPP.

the Xircom RBEM56G is assigned irq 10.

I saw a few messages in the old forums about eth0 timed out but nobody ever replied to these messages.

None The card is dropping interrupts

It sounds like an interrupt sharing problem; ensuring that interrupts
are not lost when both card functions are in simultaneous use can be
tricky.  This driver doesn't do anything special in this situation.
I'm not sure if/when it can be fixed.

Question Checking dropped interrupts

Hi Dave,

I can work with ISDN and Networking at 100-MBit/s simultanous. Are there any tools under Linux where I can check interrupt-problems in realtime while doing both ISDN and Networking? I am not familiar in the C programming language, so I cannot help developing but I can help in testing new releases of pcmcia-cs and kernels in cooperation with the RBEM56-10/100BTX card.

B.T.W. Have you descriptions for the AT command-set with the RICK ISDN Kit, I could not find them in the bypacked book or do you know where to get them?

Thanks in advance

Regards,

Stefan
