>Description:
Continously getting driver errors from sis network driver.  The error messages are as follows:

sisx: Watchdog Timeout
sisx: Applying short cable fix (reg=xx)

This is not a hardware problem like the messages indicate as this did not happen on 4.x.  Only when the machine in question was upgraded to 5.3 did the problem come to the surface.  Furthermore, when reverted back to 4.x, the problem disappears and all is normal.  I'm using Netgear FA-312 PCI network adapters.  The machine in question is running a AMD K6-2/300 CPU with 128MB Ram.  The machine has 2 identical network cards installed and is the firewall/router for the network

>How-To-Repeat:
Not sure.  Just loaded 5.3 onto the machine and it went haywire.
