System is running on Audigy 2 ZS, Opteron 248, in MSI k8t800 Master2- far. I have also been having strange issues with my DVD-RW drive, which could be related, seems as if interupt handling is not done correcty on this platform. I get random hang up's from the dvdrw, and IO errors from burn processes... here is the weird thing, I can't read DVD-R's i've burnt off on my drive, but can in almost all the other dvd roms i've tried... Anyway... Can provide more info if someone is willing to take a look at this issue. Kind regards Joel W NZ
