Re: kernel BUG at tg3.c:1557

[kwijibo@zianet.com]

I just tried this on a dual Athlon box with two 7850's in it
and a 3C996B-T as well.  Lucky for me though, this
error did not show up.  I transfered/received two 800MB files
to the RAID and it held up ok.  What driver version are you
using? Or even kernel version.
