GT64260 ethernet driver - long term stability?

[Bill Fincke <willy@synergymicro.com>]

Has anyone exercised the gt64260_eth.c driver (from the MontaVista
BK tree) for any length of time?  I ported it and have been using
it successfully for several weeks, but find that it can't sustain
continuous file transfers for more than a few hours.

I'm running a loop with ftp putting/getting a 24-MB file to a remote
Linux system, and find that after a few hours, the "put" times out.
It happens on any of the 3 ports, and to/from several different
systems (G4 Mac or PC).  I run the test on the same system through
a I82559 chip and it runs all weekend.

The only clue I have it that the driver reports a flurry of RX CRC
errors when the timeout occurs.  After ftp quits, I can ping the
remote system, but the RX packets seem to be mismatched with the
TX (ping reports once a second, but instead of ~100 usec transit
time, it reports 1.000 sec, or 2.000 sec, or 3.000 sec, as if it's
getting RX packets that are 1, 2, 3 seconds old).

Anyone else seen anything like this?
