Re: IRQ-Problem on Compaq 1720US, 2.4.18+acpi-7,24 - Help

[Huw Hawkins]

I'm no expert on dsdt tables, and in fact I've never tried to debug one
myself. But it looks to me like a device is defined on line 2292 of the
original, or 2255 of the modified asl code. as here:

-----------------------------------------------------------
Device(USB2) {
            Name(_ADR, 0x001d0002)
            OperationRegion(U2CS, PCI_Config, 0xc4, 0x4)
            Field(U2CS, DWordAcc, NoLock, Preserve) {
                U2EN,	2
            }
.
etc.
.


Since there seems to be only hubs USB0 and USB1 in lspci, perhaps the
problem lies here.

OK.  I see now.

Well, why to put that when configuring kernel.
Actually I would prefer to put an aml file in /boot
and then kernel load it, or something similar.  But it implied to hack
somewhat the way the kernel is initialized, and lilo in order to pass
the name of the file containing the AML, or using grub instead of lilo.

This is already the case under FreeBSD-current, and it is really a cool
feature.

IRQ-Problem on Compaq 1720US, 2.4.18+acpi-7,24 - Help

[Prabhakar Reddy Gudla Venkata Siva]

Hi list,

I compiled the kernel with the suggested osl.c patch and my corrected
dsdt.hex.

On bootup I get the following error (it is not the complete log):
**************************************************************************
pci_bind_0191 [22] acpi_pci_bind: Device 00:00.1d.02 not present in PCI
namespace
.....
.....
schedule_task(): keventd has not started
schedule_task(): keventd has not started
.....
.....

and that's all abt it.
**************************************************************************

However, when I did check the output of lspci on a working kernel (w/o
ACPI) there is no device on 00:00:1d.02. The o/p of lspci is below. I have
also checked it on my Windoze and there is not dev with that PCI ID.
