Hello Donald, hello everybody.
I have a problem with the realtek 8139too.c driver. In combination
with my system setup, it seems to hang the whole system whenever I
try to send PING packets larger than 1472 bytes. Probably it also
hangs the system with other applications than "ping", but I was not
able to test that yet. I have no clue why the card works for small
packets, but fails when the packets become larger.
Problem description:
I can send small ping packets up to a specific size and receive
the answer from the peer. If the packets get larger, the system
hangs. Since it's a laptop, neither the keyboard nor the soft-off
power button work anymore. I have to remove the AC power cord and
remove the battery to get the system back working... (in a rather
rude way).
When I issue:
"ping -s 1472 192.168.10.3", i get this output:
PING 192.168.10.3 (102.168.10.3): 1472 octets data
1480 octets from 192.168.10.3 icmp_seq=0 ttl=255 time=1.3 ms
1480 octets from 192.168.10.3 icmp_seq=1 ttl=255 time=1.2 ms
1480 octets from 192.168.10.3 icmp_seq=2 ttl=255 time=1.2 ms
1480 octets from 192.168.10.3 icmp_seq=3 ttl=255 time=1.2 ms
...
So 1472 data bytes are still ok. But when I try to send one more
byte of data, the following happens.
"ping -s 1473 192.168.10.3" results in:
PING 192.168.10.3 (102.168.10.3): 1573 octets data
1481 octets from 192.168.10.3 icmp_seq=0 ttl=255 time=1.5 ms
[SYSTEM HANGS]
One more interesting detail: the activity LED of the NIC still
flashes irregularly (!! - this is clearly NOT 1 Hz as it's supposed
to be when pinging). However, the activity LED at the hub's port
which the NIC is connected to DOES NOT (strange, isn't it?)
I'd be very glad if somebody could have a look at my system
configuration (see below) and point me to the right direction.
I've been trying for some days now. The card is working ok
under MS Windows ME (in a different computer however). What could
be wrong - what can I do to correct it and get it working?

1. NIC in use:
==============
- "Unex MD010C" (10/100 Mbps Fast Ethernet PC Card)
- card is connected to a 100 Mbps hub in half duplex mode

2. Kernel
=========
Kernel version is 2.4.18
- PCMCIA and CardBus support activated in kernel configuration
- Power management turned OFF (neither AGP nor ACPI)
- Kernel configuration file available upon request.
3. Driver
=========
Driver name and version: 8139too.c, Version 0.9.24
After inserting the NIC into a pcmcia slot, the system loads
the 8139too driver and logs the following messages:
