Hi!

We have three (3) machines here all with gigabit Broadcom cards. They all
display the same message "dma read modebits". All of which are HP Proliant
servers with embedded (bge) NICs.

AFAIK, we have no problems yet with the card. I just dont understand why
there's a screen output on models not beyond 575x.

I have no idea if its a harmless verbose output or something worth
investigating.

Regards,

Joseph
