Well, "work" is exactly the word to use, they work on *some* chipsets with *some* drivers, but they have problems there as well. Remember that most wintel boxes doesn't even use DMA... Besides it seems as if its our much more agressive usage thats the real problem, looks like firmware problems too me.... > Are there plans to accomodate their behavior ?

Sortof, but they dont think they have any problems at all :) -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
