Hi,
since upgrading to kernel 2.6.20 my pata disk, using new pata driver, is
initialized maximum  in DMA33 mode (and obviously performances drop 
consequently), as you can see from:

while with kernel 2.6.19.X it was initialized correctly in DMA100 mode:

I have other 2 sata disks on this system, and I have no problems with
them. I Wonder if this is due to some controller/disk problem triggered
just by 2.6.20 kernel (I saw there are a lot of changes into eh code),
while 2.6.19.X and previous sees everything OK.

Also forf the sata disks, in fact, I see this "doesn't support DPO or FUA" 
warning, but I have to admit I do not know which features it is referred to.

This system is an Athlon64 X2 3800+ with an nvidia2 IDE controller
