Re: SiI2112 + Seagate + nFroce2: no DMA!

Wonderful, so there is hope!

Yep my date was wrong because I was just coming back from flashing the 
BIOS with a new version and clearing CMOS, which did not change a darn 
thing and pushed me to send this mail :-)

RedHat seems to be releasing relatively old kernel so (what I have is 
the latest from them), must say I never paid attention to it, now I will.

Thanks so much,

Emmanuel.
