I put them at first on the same slots.. then I changed the slots to see if the trouble goes away
and got the same results. There are no shared interrupts. At this moment at PCI Device Listing
I get the NICs on irq 10 and 11, the 1st IDE on 14 and VGA on 15 ( the 2nd IDE is disabled )

I disabled DMA on ide ( with hdparm -d 0 /dev/hda ), but now I see after a few hours of traffic
going through this machine errors in logs like hell:
end_request: I/O error, dev 03:02 (hda), sector 16515104

Btw.. I don't know what you mean on the same bus segment.
