2.6.0-test4: ACPI breaks IDE/USB

2.6.0-test4: ACPI breaks IDE/USB

[Peter Lieverdink]

When I enable ACPI on 2.6.0-test4 (also on 2.6.0-test3-*), the kernel no
longer recognises my IDE controller and drops down to PIO mode for
harddisk access. Additionally, USB devices don't get detected.

Running a kernel without ACPI solves both these problems.

The system is an Athlon 2400+ on a Gibabyte GA-7VAXP mainboard. (KT400)

This is from dmesg with ACPI (CONFIG_ACPI=y) enabled:
--
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
VP_IDE: IDE controller at PCI slot 0000:00:11.1
VP_IDE: (ide_setup_pci_device:) Could not enable device.
hda: WDC WD800JB-00ETA0, ATA DISK drive
--

.. and this is with ACPI (# CONFIG_ACPI is not set) disabled:
--
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
VP_IDE: IDE controller at PCI slot 0000:00:11.1
VP_IDE: chipset revision 6
VP_IDE: not 100% native mode: will probe irqs later
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
VP_IDE: VIA vt8235 (rev 00) IDE UDMA133 controller on pci0000:00:11.1
    ide0: BM-DMA at 0xd800-0xd807, BIOS settings: hda:DMA, hdb:pio
    ide1: BM-DMA at 0xd808-0xd80f, BIOS settings: hdc:DMA, hdd:pio
hda: WDC WD800JB-00ETA0, ATA DISK drive
--

I'm happily running without ACPI now, but I guess the kernel just
shouldn't be exhibiting the above behaviour. If whomever is fixing this
bug needs more and/or more detailed info, please email me and I'll
provide it.

Cheers,
- Peter.

I'm running -test4 here with ACPI and have no trouble with USB devices.

My system is an Athlon 1000 on an MSI KT266-based board.

I'm running test4 here with ACPI and have no USB following a call trace
with "IRQ 20: nobody cared". ACPI seems to make odd reports. I've been
having this problem since 2.5.70'ish. Posted numerous times, but nobody
seems to care about it. I also have a PS/2 mouse detection when I have
no mice attached to my system.

I have a Pentium 4 2.53 GHz on a Asus P4S8X mainboard.

PS. dmesg is attached with ACPI debug and USB debug enabled.

I had similar problems with my Epox 8K9A (KT400) Board.

If I wanted to use my USB ports I had to boot wiht 'acpi=off'. But with the 
patch attached it is possible for me to boot with 'pci=noacpi'. It has the 
advantage that ACPI stays enabled...

You are free to give it a try...

Re: 2.6.0-test4: ACPI breaks IDE/USB

[Peter Lieverdink]

Hi Thomas,

Your patch works beautifully. 'acpi=nopci' previously caused IDE to work 
fine, but made the kernel not detect USB and network devices. With your 
patch it sees all peripherals AND acpi is available for the cpu. I wonder 
if it would be accepted into the kernel as a patch to workaround buggy acpi 
bioses.

Thanks heaps!

- Peter.

[PATCH][2.6.0-test4] Fix 'pci=noacpi' with buggy ACPI BIOSes

[Thomas Schlichter]

[-- Attachment #1: Type: text/plain, Size: 3453 bytes --]

Hi Andrew,

the attached patch fixes interrupt routing probems for (at least 3) people 
with broken ACPI BIOSes. If only the ACPI interrupt routing part is broken, 
'pci=noacpi' should help as the documantation states:

pci=option[,option...]
	[...]
	noacpi	[IA-32] Do not use ACPI for IRQ routing.

The problem was that ACPI interrupt routing was not correctly disabled.
The patch applies cleanly to 2.6.0-test4...

Same problem here. Without "pci=noacpi" the system doesn't detect any usb
decices, except hubs (internal ones)
Epox motherboard.
K7 650MHz

Till 2.6.0-test3-mm1 (or it was mm2?) it worked ok.
2.6.0-test4 has this problem.
The error is something about "nobody cared for interrupt #5".

I don't have more info now.

Thanks!
