2.4.21-pre6 problem with 8139too Fast Ethernet driver 0.9.26

[=?ISO-8859-2?Q?Martin_MOKREJ=A9?=]

Hi,
  I'm observing sporadic problems with my onboard network card:

$ ping 195.113.56.1

I saw these error with 2.4.19, 2.4.20 and most subsequequent testing releases. I
cannot say about older kernels, as I did not have that machine before. Could
anyone tell me what kind of information should I gather to make it reproducible
for you?

It seems at least now it appears when I do "mii-tool --reset" and continues:
