Box freezes if I enable "AMD 76x native power management"

Box freezes if I enable "AMD 76x native power management"

[Oleg Drokin]

Hello!

   Starting from 2.4.20 until now (including 2.4.21-pre4 and 2.4.21-pre4-ac5",
   whenever I enable "AMD 76x native power management" in my kernel config, I get
   kernel that hangs at boot after reporting elevator stuff about my IDE drives.
   Is anybody interested?

   I have dual-cpu Athlon-1700+ on some Tyan MB:
PCI devices found:
  Bus  0, device   0, function  0:
    Host bridge: Advanced Micro Devices [AMD] AMD-760 MP [IGD4-2P] System Controller (rev 17).

It doesnt work with some tyan boards. I've never found out why. Most of them you
load the module, it stops, you poke the button and it wakes up again and then works

This is not my case it seems. No matter what I press, it is dead.
But I compile it statically into kernel, though. Have not tried with a
module yet, though.

I am.  This sounds suspiciously like the bug I reported.

But you haven't given quite enough information for me to compare.  Can
you send:

1) Exact Mother board (Tyan what?  Tiger MPX 2466N . . . ?)
2) Do you have DMA turned on for your IDE drives?
3) Are you enabling the AMD chip support for IDE?

. . . and anything else you can find out about the box?

Most importantly . . . does the problem go away if you turn off DMA
support for IDE?

Thanks,
John S.

I have some problems with this hardware, too. Maybe I can provide some 
useful bugreports - I'd gladly do some tests with the 2.4.x kernels if 
someone is interested (I only tried 2.4.19 and 2.4.20 with this 
hardware so far).

I have a Tyan S2466N-4M (Tiger MPX, Chipset AMD 760MPX, 762, 768), 
2x Athlon MP 2000+, 
512MB Reg. ECC SDRAM
2-3 IDE drives and a DVD-ROM on the onboard channels
DMA support enabled (I don't like to disable this, because when I copy 
over 100MB from the DVD to a harddrive with DMA disabled the cpu-usage 
wents well above 50% and then the machine _freezes_.)

With 2.4.19, the power-switch didn't work after shutdown (It works now 
with 2.4.20). Automatic power-off (halt -p) doesn't work with neighter 
2.4.19 nor 2.4.20. 

With "AMD 76x native power management" I experienced freezes under X11 
when the system was idle for about 30 min that usually went away when I 
typed on the keyboard. Using the (USB) mouse had no effect. But I had 
no problems at boot-time.

I've seen this too, but only in certain kernels.  Someone needs to take 
the time to binary search the pre patches to track down which one 
introduced the problem...

Hm.

Tyan Tiger MP (bios v1.03)

> 2) Do you have DMA turned on for your IDE drives?

Yes. Tried to boot with "ide=nodma". It hung too, but
first emitted about set_drive_speed_blah: ... error messages.

> 3) Are you enabling the AMD chip support for IDE?

Yes. I tried to disable "AMD Viper" IDE support in kernel,
but that did not help.

> . . . and anything else you can find out about the box?

Well, dual cpu athlon 1700+, 1G RAM. 2 IDE disks on primary channel.
Geforce3 video card. Some cheap cmpci sound board.
That's it.

No.

Just another voice in the crowd...

TYAN 2462 dual 1200MP, and another w/ dual 1900MP
Dual WD100 IDE, seperate channels
Current BIOS 2.13
1GB RAM

I noticed this behavior when I started playing with 2.4.20 and could
never figger it out - went so far as to bring up KGDB and was way down
in the IDE DMA code, scary stuff... Kept scanning LKML and finally found
this gem of a thread...

Ran up a clean, fresh kernel from pre4-ac5, four combos
1) CONFIG_AMD_PM768=Y CONFIG_BLK_DEV_IDEDMA_PCI=y
2) CONFIG_AMD_PM768=m CONFIG_BLK_DEV_IDEDMA_PCI=y
3) CONFIG_AMD_PM768=Y CONFIG_BLK_DEV_IDEDMA_PCI is not set
4) CONFIG_AMD_PM768=m CONFIG_BLK_DEV_IDEDMA_PCI is not set

In cases 1 and 3, hang at boot, pressing the power button frees it up.
In cases 2 and 4, no boot hang, and, at lease for me, no hang when
amd76x_pm module's loaded

So, back to playing - if you need some testing on this board, let me
know - I use one at work and one at home, takes no time at all to gen up
and try things out, and they'll get pretty good exercise.

Gio
