Subject: Re: port-i386/34025: ACPI Interrupt Failure with 3.99.22 (and  3.99.21)
Date: Sat, 12 Aug 2006 18:25:38 +0200

 Can you try to build a kernel from -current sources, which include 
 sys/arch/x86/x86/mpacpi.c rev 1.38, and sys/arch/x86/x86/acpi_machdep.c 
 rev 1.11?
 
 I fixed one way that the ACPI SCI interrupt could get screwed up, but I 
 can't verify if that matches what you are seeing.
