 Posted: Fri Sep 16, 2005 12:14 pm Post subject: acpi issues .... (IRQ conflicts ?????) |
 |
|
I am trying to set my new laptop, the only problems i have is that pc speakers and smartlink modem won't work. i ve tried many things, posted sever threads but nothing worked. It just occured to me that perhaps ACPI irq handling is to blame...
so here i post mime ACPI outputs hoping that you will help me debug all this wird irq conflict stuff!!!!

As you can see ACPI power managemenr work extremely well, but what about all those interrupts???

thanasis@KLG_laptop ~ $ cat /proc/interrupts

I wonder if your new Laptop supports APIC interrupt handling?
Maybe that could help with the errors as I have turned APIC off in my BIOS and it looked similar to yrs.
Oh yes and if it is supported you must enable it in the Kernel as well.
Good luck. |

how do i check that?
unfortunately, my bios has a very few options.
Enable APIC from kernel....
Again emerge everything..... nvidia, realtek, spca5xx, ipw2200, ..... |
