[Gllug] Intermittent Network Loss on Centos Web Server

Actually the only network card I have *ever* had problems with at
installation time was an Intel e1000e: the out-of-tree driver worked
but was rather tricky to install with no network connection (a USB key
did the trick), and the in-tree driver at the time transmitted about
ten packets before hitting a nasty race, going silent, and maxing out
a couple of cores with an IRQ flood.

(This was a temporary thing, covering 2.6.30--2.6.30.4, but still.)

Mind you I just lost a non-Intel network card to apparent static shock
because I dared the radical and unexpected act of plugging a network
cable into it (floods of 'spurious IRQ' followed by the card vanishing
forever off the PCI bus), so perhaps other cards suck as badly.
