That means kernel panic.

I don't think so, probably it's a NIC driver problem
Which Intel driver are you using?
If it's the e100 or the eepro100 you first could try to use the other driver,
I had problems with the Intel driver (e100) but the eepro100 driver works
without problems.

You also could try downgrade the kernel to that 2.4.16 and see if that solves
the problem.

I don't think so, but if it is a NIC driver problem it wouldn't solve the
problem.

If it's still possible you could look at tty10 (press <ALT> F10), maybe there
are some messages there which doesn't get written to the logfiles due to the
freeze.
