AHCI is a pretty well tested driver, but 99%+ of all testers still 
tend to have less than 4GB of memory. So I do *not* believe that the 
highmem bits are all that well tested at all.
Can somebody who knows the driver send Marco a test-patch to just 
limit DMA to the low 32 bits, and then Marco can at least verify that 
yes, that that it. While it looks like DMA problems, there could 
obviously be some other subtle issue with big-memory machines (ie the 
PCI allocations etc tend to change too!)

We have another outstanding bug report of a Marvell chipset being
used in a funky 32-bit PPC situation with memory above the 4GB mark.

Possibly related, possibly not.

The Marvell SATA driver is still VERY EXPERIMENTAL right now,
missing some errata and stuff.  This should improve over the next few 
months.

Hello,

I don't have a Marvell chipset. I didn't compiled in this. I have a 
"Intel Corporation PT IDER Controller" and an intel matrix storage 
controller. So I think it doesn't concern my case...
