2.6.14-rc2-mm1 ide problems on AMD64

Hi Andrew,

2.6.14-rc2-mm1 doesn't seem to boot on my AMD64 box. It hangs
while probing "ide" disks. I spent time looking at it and
here is what I know so far.

2.6.13: works fine
2.6.13-mm series: works fine
2.6.14-rc2: works fine
2.6.14-rc2 + linus.patch (from -mm1): works fine
2.6.14-rc2-mm1: hangs on boot

I looked through all the changes in "drivers/ide/" in -mm
and none of them seemed to cause the problem. I added tracing
to figure out whats happening. It hangs while doing, "do_probe()"
Here is the calling sequence:

ide_scan_pcidev()
amd74xx_probe()
ide_setup_pci_device()
probe_hwif_init_with_fixup()
probe_hwif()
probe_for_drive()
do_probe()

If anyone has fixes/debug to try, please let me know.

Thanks,
Badari

If you have quilt(1) installed and don't mind a couple recompiles, you
can do a bisection on -mm patches:

1) Unpack clean 2.6.14-rc2.
2) Apply attached patch to it ("bisect-mm" script).
3) chmod 755 ./bisect-mm

4) cp -r $WHATEVER/broken-out patches # copy broken out -mm to the top
# level directory

"Dumb" mode:

5) ./bisect-mm start
6) ./bisect-mm apply
# wait until patches are applied
# or reverted
7) rebuild
reboot
8) ./bisect-mm good # if it boots fine, or
./bisect-mm bad
goto 6

Continue until it says "Sucker is ...".

You can also enter "smart" mode after reading comment at the beginning
of the script. It can save your some recompiles.

Well, I tried using your script to bisect -mm patches.

I did steps (1) - (7) without problem. Then my kernel didn't boot.
So I did

./bisect-mm bad
./bisect-mm apply

I get following messages infinitely. Seems to be problem with
scripts/quilt.

Anyway, I will do manual binary search.

Thanks,
Badari

Or just do the bisection search by hand.
Either way, can you please find the time to do this? I have no idea
what broke it.
Except maybe acpi. Try just linus.patch and git-acpi.patch, perhaps.

Subject: Re: 2.6.14-rc2-mm1 ide problems on AMD64

Finally, tracked the problem causing patch in -mm tree.
Its,

x86_64-no-idle-tick.patch

I backed out the patch and my machine works fine.

Thanks,
Badari

Boot message please.

Did you enable CONFIG_NO_IDLE_TICK?
