Uhm, 'fixed' may be premature: I restarted the machine and with 22
hours uptime I am getting:
tx_deferred_ok: 36254

I most certainly can. This seems to have gotten worse by a factor or
100 or more.. so am I to suspect the new cable?

True, but I tried changing the switch ports with little change.
Putting a client on the same switch port yielded no errors on the

The switch, btw, is a fairly generic GS108 from Netgear (there
actually are two).
