This is my first problem ever with the kernel, and also my first mail to
linux-kernel so please be gentle...  I have followed the list a bit
though.  

The format of this mail is as recommended in "REPORTING-BUGS" in the
kernel source.  Sorry about the length, but I'm just following
documented procedure.  :P

Without further ado...

** The problem
I was having corruption issues with my onboard highpoint controller
(HPT366, Abit BE6 motherboard) when the PCI bus was being utilized
heavily (reading from the 4 drives and sending over 3com ethernet), and
I've read in several places that the highpoint controller is buggy.  I
picked up a Promise Ultra100 controller in hopes that things would work.

I rebooted the machine and realized I hadn't compiled the Promise driver
into my kernel - the machine booted fine at this point and found all of
my drives, but performance was horrible (2-3MB/sec instead of 10+) so I
recompiled and rebooted.  When I reboot with the Promise driver
compiled, the boot process looks like so:

Uniform Multi-Platform E-IDE driver Revision: 6.31

hda: Maxtor 91024U4, ATA DISK drive
hdc: TOSHIBA DVD-ROM SD-M1212, ATAPI CD/DVD-ROM drive

hda: 19999728 sectors (10240 MB) w/2048KiB Cache, CHS=1244/255/63,
UDMA(33)
***[HANG]***

The machine finds the controller and the drives attached to it, but
while attempting to determine the hardware settings from the drives
attached to the promise controller it hangs.  /dev/hda is on the intel
chipset controller and thus works fine.  Keyboard stops working, can't
reboot, etc.  Without the Promise driver compiled, my (relevant) output
after that point looks like:
...
hde: 26684784 sectors (13663 MB) w/2048KiB Cache, CHS=26473/16/63
hdf: 40020624 sectors (20491 MB) w/2048KiB Cache, CHS=39703/16/63
hdg: 60030432 sectors (30736 MB) w/2048KiB Cache, CHS=59554/16/63
hdh: 156301488 sectors (80026 MB) w/2000KiB Cache, CHS=155061/16/63
hdc: ATAPI 32X DVD-ROM drive, 256kB Cache, UDMA(33)
Uniform CD-ROM driver Revision: 3.12
Partition check:
 hda: hda1 hda2 hda3 < hda5 hda6 hda7 >
 hde: [PTBL] [1661/255/63] hde1
 hdf: hdf1
 hdg: hdg1
 hdh: hdh1
... etc

Note that booting without the promise driver and just using generic IDE
DOES work, but with dismal performance on the drives attached to the
promise controller along with high CPU usage.  They don't claim to be in
PIO mode when I hdparm -i them, but they feel like they are.

I played around a bit and then thought of feeding the drive geometry to
the driver with LILO boot: parameters.  I used the following line -
LILO boot: linux-new hde=1661,255,63 hde=noprobe hdf=39703,16,63
hdf=noprobe hdg=155061,16,63 hdg=noprobe hdh=59554,16,63 hdh=noprobe

When I boot like this, the machine gets to the same point in the boot
process (the hda: 19999728 sectors above) and then throws an oops (see
below) and panics.  Note that I am not using modules at all, and I
couldn't easily get /proc/ksyms because it happens before I even get a
prompt and the machine is dead hung afterwards.  (Thus why I used
ksymoops -K)

I have *not* tried this on older kernels, nor have I tried any of the
-pre* series.  If anyone thinks either of these could help I'm willing
to give it a try.  I'm waiting on another motherboard from a friend -
the only other possible cause of this that I can think of is that the
HPT366 controller is somehow confusing the Promise controller.  I can't
turn off the HPT366 on this motherboard, there is no disable in the
system bios.  The Promise card is known-good; it worked fine in my
friend's Windows system and in his linux system a while ago (kernel
unknown) before I bought the card from him.

I hope this helps the people it needs to... I'll be lurking around if
anyone wants clarification on anything or has helpful suggestions to
offer.

Thanks in advance, and I appreciate the work that everyone does to make
