Hi,

I got this SATA PCI card:

It worked very well for half a year but with one disk (IIRC it was even plugged into second channel but I wont bet on it). Now I have second disk (very similar) and it is always put into PIO4 mode:

As you probably know this gives very very poor performance. Is there any way to make it fast? I tried changing cables and reconnecting them but it looks like it does not help. I can't do too much with this hardware since it is used as production server. But testing some patches is of course possible. On the other hand full kernel upgrade to 2.6.19 or .20 is not possible because this kernel has openvz patches and I don't have them for .19 or .20 yet.


This is what I am getting from various utilities:
