Ok, well the more happy the people who have the ability to know what the
problem is the better so despite a simple usb issue, moving out of devfs
wasn't a hassle. I'm willing to move back to vanilla if it helps in
chasing a problem down. I'm just kind of disappointed that the
discussion of me playing around with devfs got more attention from the
ide guys than the actual problem since it seems to be strictly DMA
related and not a drive problem so if it's chipset conflicts it should
be documented either in the good-bad firmware so the kernel disables dma
on boot of this particular promise chipset when this particular via
chipset is present or in the HELP for the config option so at least
users are aware that drive corruption has been known to happen on the
linux promise driver when dma is enabled on some via chipsets. That is
unless it's a fixable problem. Which i rather hope it is. neither the
abit motherboard or promise controller card are uncommon. But since
nobody i know has via + promise setups I cant ask them to run the
cerberus test to see the same behavior to see the extent of the promise
+ via problems or if it's even got anything to do with via. (shrugs)
