Subject: kernels 2.6.29.rc3 2.1 3.1 4.1 5.1 6.1 7.1 and rc4 8.1 Is ACPI broken
???????
hi all
the second posting went wrong due tot gmail problem (network)
this is /proc/interrupts
did the following run with full acpi
CPU0 CPU1 CPU2 CPU3
0: 97 0 0 0 IO-APIC-edge timer
1: 7310 0 0 0 IO-APIC-edge i8042
7: 1 0 0 0 IO-APIC-edge
8: 1 0 0 0 IO-APIC-edge rtc0
9: 0 0 0 0 IO-APIC-fasteoi acpi
12: 115 36083 0 0 IO-APIC-edge i8042
14: 8029 0 0 0 IO-APIC-edge pata_amd
15: 0 0 0 0 IO-APIC-edge pata_amd

then run with no acpi

in both cases irq-balancer is running
see the difference in IO-APIC-edge i8042
This is a raid 0 system
in the acpi run irq 22 23 is the raid array
and in the no acpi run irq 5 7 is the raid array
all togethher the no acpi run gives a more equal load on the 4 cpu's
as the acpi run gives 0 60 to 90 % load on cpu 0 the other cpu's not
more then 4 to 10 percent with intervals
hope this gives you more info in what i mean
2.6.27 kernels acted more like the no acpi setting.
and no warning on the acpi tables in the bios
