It's a little too technical for me, but let me add
the components of one of my trouble PCs:
atapci0: <VIA 82C596B UDMA66 controller>
ad0: 43979MB <IBM-DTLA-307045/TX6OA50C> [89355/16/63]
at ata0-master PIO4
acd0: CDROM <CRD-8520B/1.00> at ata1-master PIO4
The harddisk can do UDMA100, but if I let FreeBSD 5.3
sort it out by itself, the kernel panics at bootup.
Modifying loader.conf, forces my fast harddisk to
operate at PIO4 mode, which is far from optimum; it
should at least be able to operate at UDMA66 !!
FreeBSD 5.3 is not capable of solving this properly.
This observation I could not find in your PR report.
Regards,
Rob.
