kernel: bge0: watchdog timeout -- resetting

[Kev]

I had similar problems with the rl realtek driver with 5.3 and 5.4

A number of things seemed to relieve the problem (disable acpi, free up 
interrupts / make sure the nic wasn't sharing one) but it inevitably 
came back.

The stalling seemed quite random, I could push tens of gigabytes through 
...idle the connection for a day or so then transfer 200k and it would 
fall over.

There did seem to be a small correlation to transfer speed. The higher 
the speed the more likely it was to fall over. Transferring a 100mb file 
at 10 megabytes a second was more likely to fail than transferring a 
100mb file at 100k a second.

I didn't do much more digging (didn't have time and I don't have the 
knowledge without guidance) instead I switched nic and am now using the 
fxp intel driver with no problems.

I had the problems on a single cpu celeron box using both GENERIC kernel 
and custom kernels (with unused device drivers stripped out to free irqs).

I came across a number of other people via google having the same 
problem. Predominantly with the rl driver but also with others. What 
seemed to work for some people failed for others.

Have you made any hardware changes?
