I'm experiencing a similar problem, but with kernel 2.2.11 (and on a much smaller machine: a 200MMX, with 3C509 ethernet card.)
On HIGH network loads, e.g. 5M file copy via NFS or rcp to/from a Solaris server on the same LAN, the PC freezes up as follows:
- mouse, keyboard do not work any more - I cannot telnet to it - I cannot get date via UDP - I CAN ping it
So the ethernet card works, ICMP works, while TCP and UDP do not. (Or, at least, telnet and date services are down).
