>Description:
When booting the generic 4.5 Release i386 kernel with a 160gb Maxtor
drive (4G160J8) attached to a Promise pdc20265r controller the
kernel stops with trap 12. Bootdisk is a SCSI hardisk, there are no
other ata drives attached. When attaching the drive to ata3-master,
then boot -v shows:
...
ata2-master: ata_command: timeout waiting for intr
ata2-master: identify failed
ata3-master: success setting UDMA5 on Promise chip

Variations:
-----------
Setup:
A naked system with graphics card, zero to two 3com 3c905ctx,
booting via SCSI disk a 4.5 Release, no other ata disks attached
except the 160gb Maxtor drive. The Promise does not share the IRQ
with other hardware.
WORKS = no problems when doing disklabel, newfs, mount and
dd if=/dev/zero of='many megabytes' to the Maxtor disk
FAILS = boot fails as shown above
Asus A7V133 Via/Athlon with onboard Promise pdc20265r
Maxtor 80G @ VIA (ad0..3) : WORKS
Maxtor 160G @ VIA (ad0..3) : WORKS
Maxtor 80G @ Promise (ad4..7) : WORKS
Maxtor 160G @ Promise (ad4..7) : FAILS
Asus TUSL2 Intel i815E-B with onboard Promise pdc20265r
Maxtor 80G @ Intel (ad0..3) : WORKS
Maxtor 160G @ Intel (ad0..3) : WORKS
Maxtor 80G @ Promise (ad4..7) : WORKS
Maxtor 160G @ Promise (ad4..7) : FAILS
Abit KT133 Intel BX 440 with onboard Highpoint HPT 370
Maxtor 80G @ Intel (ad0..3) : WORKS
Maxtor 160G @ Intel (ad0..3) : WORKS
Maxtor 80G @ Highpoint (ad4..7) : WORKS
Maxtor 160G @ Highpoint (ad4..7) : WORKS
(Note: Although the Abit's name is KT133 it's a BX chipset)
It seems to be a problem with Promise and the new adressing
for disks > 130 GB (?)
>How-To-Repeat:
Connect a Maxtor 160G disk (4G160J8) to a Promise PDC20265R and
boot the 4.5 Release GENERIC kernel
>Fix:
sorry, no
