[ACPI-sppt] write to /proc/acpi/alarm causes irq 9: nobody cared!

Hi 

When echoing a wake-up date to /proc/acpi/alarm, I get the following message:

irq 9: nobody cared!
Call Trace:
 [<c010d48a>] __report_bad_irq+0x2a/0x90

handlers:
[<c02319c3>] (acpi_irq+0x0/0x16)
Disabling IRQ #9

Below is my dmesg. I am using an MSI KT400 ultra board with recent BIOS. 
The kernel is 2.6.0-test1 with Alan Cox's ac1 patch applied. 
Would any other information be useful in debugging this problem?
Does anybody have any suggestions on what might be wrong?

Thanks

PS. When I try the latest ACPI patch applied to kernel 2.4.22-pre5, echoing a 
wake-up date to /proc/acpi/alarm causes the machine to crash. Perhaps it is 
the same problem as above, just not so elegantly handled?
