I applied that diff file to my source tree, and made the module.
I loaded the module and did the same tests that i did before.

kernel: eth0: Tx queue start entry 44186  dirty entry 44186.
kernel: eth0:  Tx descriptor 0 is 0008a5ea.
kernel: eth0:  Tx descriptor 1 is 0008a5ea.
kernel: eth0:  Tx descriptor 2 is 0008a5ea. (queue head)
kernel: eth0:  Tx descriptor 3 is 0008a5ea.
kernel: Assertion failed! rp->mapping !=0,8139too.c,rtl8139_tx_timeout,
line=1491

  [ -- at this point, the card is still working fine -- ]

but then after putting more load on, the card "froze" just like it did
using the rtl8139.c driver. i checked the version numbers in the patched
8139too file, they are the same as the ones on the webpage.

Thanks,
