------- Comment #28 from [EMAIL PROTECTED] 2008-04-10 19:59 -------
Hi, Alexandru
Thanks for the info.
From the log in comment #27 it seems that the system can work well when the
system is booted in PIC mode with acpi enabled. And it is confirmed that the
second problem is caused by the incorrect PCI interrupt
routing.(pci=noacpi/acpi=off).
In your laptop there is no MPS table /bios PRT table , which includes the
info of PCI interrupt routing. When the system is booted with
pci=noacpi/acpi=off , OSPM will read the irq number directly from the PCI
device config space and request the interrupt handler for the device.
Unfortunately the IRQ number of some PCI devices is incorrect. So OS will
report the error message " IRQ 10 nobody cared".
For example: 06.01.2 device:
The irq number of PCI config space is 0x0b.
The irq number in PIC mode is 0x0a.
> ACPI: PCI Interrupt 0000:06:01.2[A] -> Link [LNKG] -> GSI 10 (level, low)
-> IRQ 10
Because the system can work well with acpi enabled, it is unnecessary to fix
this problem.
