I may have presented my question in a confusing way,
mixing in 2 PCs, 2 dmesg'es and a variety of issues. Excuse me.

These issues sound like they are related to lack of software support driven by
a lack of programming documentation.
The pciide driver doesn't support your Nvidia chipset. It needs extra
code (specific for this chip) for DMA to work properly.
The driver was targeted towards older systems, it shouldn't be used on any
board that supports AHCI. AHCI has more capabilities including NCQ and will
offer better
I believe it was the
nVIDIA nForce 570 SLI
chipset of Asus M2N-E motherboard that caused 3 kinds of errors,
one kind being a multitude of:
wd0(pciide1:0:0): timeout
type: ata
c_bcount: 16384
c_skip: 0
pciide1:0:0: bus-master DMA error: missing interrupt, status=0x21
wd0a:
4 matches
