Freezing problem with 3C 3c905B and 3c59x.c:v0.99E driver

As an update, with many thanks to Brian Winters and Shon Martin for 
their helpful responses, my freezing problems appear to have been
fixed after updating to the 3c59x.c:v0.99L 5/28/99 driver.

However, based on an initial look, it appears that the overall
data transfer rate from the machine seems to have dropped quite a
bit. I am not completely sure of this, but iptrafx shows me lower
transfer rates (it appeared to have peaked at about 4Mbits/sec as
opposed to the 9.5Mbits/sec rate I saw earlier) for the same scenario.

Any thoughts on the possible slower data transfer?

Best Regards,
