> So anyway, what's actually failing is one of these: Thanks for the analysis. In theory we could not fail DAC if the machine has <4GB RAM to work around such buggy drivers, but then they would fail anyways with >4GB. Also the failure was intended to allow some drivers to use more efficient non DAC operation. > It seems a bit mean to write off *all* VIA bridges as data-corruptors. > Maybe the people who haven't had problems before can help us start a > white-list of VIA PCI bridges that don't have a problem with DAC. The reason I blacklisted all was that there was a small triple of data corruption reports with VIA bridges. Also it's impossible to get any errata information out of VIA. And there are not that many >4GB VIA systems because these chipsets are usually used in lower end systems. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
