Re: FAUmachine: Looking for a good documented DMA bus master capable PCI IDE Controller card

Hello,

I just talked with a coworker who has experience with the above card. He
told me that this IDE controller (hardware) has havy problems if you
have havy load on both channels. (Blue screens in windows and DMA errors
in Linux).

He also told me that everything works fine if you use one channel in PIO
mode and that there are workarounds in the linux kernel to circumvent
the upcomming problems under havy load.

Is that true or just nonsense?

However it is worth to look at them. Thanks for the pointer! :-)
