Hello,
The system is as follows:
- Intel CA810EAL motherboard (built-in EtherExpress Pro 10/100)
- 128MB RAM
- 10GB IDE HD (Western Digital WD100)
- Linux kernel 2.2.18
Sometimes when I reboot the system, as soon as the eepro100 module is
loaded, I start to get these msgs on the screen:
eth0: card reports no resources.
eth0: card reports no RX buffers.
eth0: card reports no resources.
eth0: card reports no RX buffers.
eth0: card reports no resources.
eth0: card reports no RX buffers.
(...)
They go on forever, and the box becomes inoperational (I can see the msgs
on the screen, but I can't login, type anything ...). If I reboot the
system, the msgs do NOT show up anymore, and then I can use the system
again.
Could anyone _please_ shed a light on this one for me?!?! How could I
solve it?? What kind of additional info you need?? Please let me know.
Later,
Ivan

Does the following patch, taken from 2.4.1, help?

It is better to keep your mouth shut and be thought a fool,
than to open it and remove all doubt.

I'm currently testing. I'll get back to you soon (have to reboot the
system a lot to make sure it's really solved ... :)).
Thanks for the quick response!!

Yes, the patch did solve the problem.
Alan, could you please include this patch on your 2.2.19pre series (if
it's not already included)??
Ion, thanks again for your help!!
