Problem with gem network card
Hi,
on my Mac G5 I see loss of network connectivity when doing big downloads
or uploads.
The machine cannot be pinged anymore then and also cannot ping out.
When it's happening I see the following messages:
Oct 11 10:45:13 g5 kernel: [ 430.477967] gem 0001:04:0f.0 eth0: RX MAC
fifo overflow smac[03810400]
