Hi,Alexandru
Sorry for the delay.
From the logs it seems that there are two problems about your laptop.
a. there exists the following message when acpi is enabled.
>PCI: Cannot allocate resource region 7 of bridge 0000:00:1c.0
>PCI: Cannot allocate resource region 8 of bridge 0000:00:1c.0
>PCI: Cannot allocate resource region 9 of bridge 0000:00:1c.0
>PCI: Cannot allocate resource region 7 of bridge 0000:00:1c.1
>PCI: Cannot allocate resource region 8 of bridge 0000:00:1c.1
>PCI: Cannot allocate resource region 9 of bridge 0000:00:1c.1
>PCI: Cannot allocate resource region 7 of bridge 0000:00:1c.2
>PCI: Cannot allocate resource region 8 of bridge 0000:00:1c.2
>PCI: Cannot allocate resource region 9 of bridge 0000:00:1c.2
The above message won't break anything and it is harmless. Maybe the above
message is related with that some configure setting of some PCI
devices(1c.0,1c.1,1c.2) will be changed in the course of mode transition from
legacy mode to acpi mode(not sure). When the system is booted with the option
of "pci=noacpi", OSPM will also use the same legacy PCI scan mechanism as the
boot option of "acpi=off". The only difference is that acpi is enabled in case
of "pci=noacpi". Maybe the configure settings of some devices will be changed
when the system is switched from legacy mode to ACPI mode.
Because the above message is harmless, it is not worth spending more time on
it.
b. the error message "IRQ 10 nobody cared" on 2.6.24-rc5 kernel with acpi=off
or "pci=noacpi"
It seems that this is related with PCI interrupt routing.(pci=noacpi/
acpi=off).
Will you please try to boot the system with the option of "noapic
acpi_irq_nobalance" and attach the output of dmesg, /proc/interrupts?
Thanks.
