A transmit reclaim error. This means that someone has caused a
collision after the NIC has transmitted more than 128 bytes of a
particular frame.

Are you really, really sure that there isn't something on the network
which is erroneously operating in full duplex mode? According to
http://www.scyld.com/network/vortex.html, a reclaim ("out of window")
error is due to a network problem.
You're on a half-duplex LAN, right? 10 or 100 mbit? Are you using the
BNC or AUI interfaces? Are there many other hosts on that LAN?
It is possible that the driver is deciding to start operating with the
wrong media interface or duplex, but it's hard to explain how this could
cause such very late collisions.
As a last resort, if you're sure it's not a LAN prob could you please
try forcing the driver into the correct media settings with
'options=0xNN' and perhaps 'full_duplex=1' as per the instructions at
http://www.scyld.com/network/vortex.html?
Thanks.
