Re: Kernel or patch suggestions for DMA enables Marvell Driver

[Terrence Martin <tmartin@physics.ucsd.edu>]

In my case this is actually an onboard Marvell Sata controller. There is 
nothing in the two PCI-X slots at all. :(

I am going to ask Supermicro what the story is. Even the driver from 
Marvell that I have code for, of which I have found several versions, 
refuses to work correctly either on the Xeon system below or some new 
Opteron systems.

In any case I am happy to work with whoever is making the linux kernel 
driver for marvell to try to get to the bottom of the issue. I could 
even provide a login on a dedicated system if that would help.

Cheers,

Terrence
