Re: Fw: [Bugme-new] [Bug 3765] New: Network link down, when writting to sata disk AND network in use

[Surakshan Mendis <surakshan@surasoft.com>]

FYI 

I've just added a realtek based card using the 8139too kernel module.
The "issue" mention below DOES NOT happen with this network card. Only
with the onboard b44 card!
