The PCNET32 driver (compiled as a module) frequently hangs when moderate
amounts of information is transmitted. A "eth0: transmit timed out, status
007b, resetting" kermel log message is generated. I have tried changing
default buffer sizes in the driver source code to no avail.
Further information below, including Ring Data Dump.

Changes made to default buffer sizes in pcnet32.c (to no avail)
-------------------------------------------------
* #define PCNET32_LOG_TX_BUFFERS was 4 changed to 2 then 8
* #define PCNET32_LOG_RX_BUFFERS was 5 changed to 2 then 5
