Yes, that's about it. Number 1 seemed to cause the most crashes, I don't think number 2 ever caused any problems, but it might have, there were too many weird oopses to be able to rule that out. But in the end, I don't think that PCI really will benefit from this speed wise, but I think the kernel overall will benefit if we can document those dependencies somehow. thanks, greg k-h - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
