--- Comment #12 from ykzhao <[email protected]> 2009-07-06 03:49:12 --- Hi, Zbignew From the info in comment #10 it seems that the interrupt pin of OHCI is routed to 20/22 of I/O APIC on windows. But from the info in comment #6 it seems that sometimes the interrupt pin of OHCI is routed to 21/22 of I/O APIC. Sometimes it is routed to 20/22 of I/O APIC. When the boot option of "noapic" or "acpi=noirq" is added, it will use the I8259 instead of I/O APIC. But it is strange that the OHCI can work well if the I8259 is used. But it can't work well under the I/O APIC mode. And from the acpidump it seems that still link device is used even when it works in I/O APIC mode. I don't know whether this is related with the BIOS/hardware. thanks. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ _______________________________________________ acpi-bugzilla mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
