Greetings;

Just built bk7 after running the bk4-kjt1 version for a cpouple of 
days, and noticed this in /var/log/dmesg:

>From grub.conf to dmesg:
Kernel command line: ro root=/dev/hda7 acpi_skip_timer_override

Then, quite a ways down in that logfile:
irq 12: nobody cared!

Disabling IRQ #12
serio: i8042 AUX port at 0x60,0x64 irq 12

Which seems a bit odd, to didsable it, and immediately enable it.

Anyway, a cat of /proc/interrupts:
[root@coyote CIO-DIO96]# cat /proc/interrupts

Which shows that ACPI didn't manage to seperate them all.

Is there a quick cli based fix to put into that grub.conf entry?
