No problems. Here's the log of unworking kernel with IOMMU turned on.
Basically it goes on reseting the SATA ports throwing many errors (none are
present in 2.6.23 or on 2.6.24-rc with mem=3500M

Hmmm.. weird. The workaround is still there. Please post boot log.
OK, that's good to hear. Alas, after the Fedora 7 to 8 upgrade, I'm no longer
able to compile a kernel (some uhci-hcd module not found for the initrd). And
I was too quick to overwrite

With mem=3500M all is well, otherwise it goes on reseting the ports in a loop

Srihari, can you test this against 2.6.22-rc1-git7 just in case? I'll
send this upstream after you ack.
It's merged in today's git (quickly tested it it's working good as expected)
:-).

Can the Skymaster S3132, based on Sil3132,
(http://umart.net/au/product_info.php?cPath=21_211products_id=106108) do
64
bit DMA on Linux?
Yeah, sil3124/32 can do 64bit

Tejun,
Of course. Yes, it's working great without mem=4095M

Oh well, that's the price you have to pay when you 1. have a device

It just seems sb600 claims that it can do DMA above 4G while it actually

Thank you for your insight into the problem. If there are any tricks
involved
in making use of all 4 GB of RAM with SATA drives with system stability,
I'll be very happy to learn them :-)).
