Hi netllama & zander,
I will build a vanilla kernel to check, although the gentoo patches are fairly minimal.
As far as the BIOS, I'm running 1205 which is not the latest, but close.
1305 is stable, 1405 is beta, which do you recommend?
zander, yes the card is seated properly.
Regarding possible DMA transfer corruption, how would I check this?
Would it be beneficial for me to post my kernel config?
It is already posted on gentoo forums here:
Someone mentioned kernel headers possibly causing an issue, but I can not see this issue on any other machine that I have control over.
