IDE DMA issue or not ?

IDE DMA issue or not ?

Hi folks,

I'm reading here and there about IDE DMA support in Xen 2.0.x
because it did not work for me (2.6.10). What should I expect
on the stable tree? What about the comments at
http://www.suse.de/~garloff/linux/xen/ about IDE DMA ?

I hope to get some first hand infos.

To the best of my knowledge most of the commonly used IDE chipsets are 
supported.  I'm not aware of any that Linux supports that Xen doesn't 
support (although I could be wrong).

IDE DMA support is perhaps one of the most common user problems with 
Xen.  The default Xen config does not compile support in for most of the 
IDE chipsets.  You most likely have to recompile your kernel sources and 
add the appropriate support for your chipset.
