Right, I inserted an infinite loop in drivers/acpi/sleep/main.c, just after  
printk(KERN_DEBUG "Back to C!\n"); in acpi_pm_enter()

        /* Johnny's infinite loop */
        for (;;) ;

However, the computer must have rebooted before then. Next thing I tried was 
an infinite loop in arch/i386/kernel/acpi/wakeup.S as the first thing for the 
wakeup_start routine.

ENTRY(wakeup_start)
wakeup_code:
        wakeup_code_start = .
        .code16

1:
        jmp      1b

This too, doesn't catch it. This makes me think that perhaps there is 
something going wrong with the ACPI wake-up address initialisation?

My dmesg (with acpi debugging enabled) is at http://www.doc.ic.ac.uk/~jak97/
dsdt/dmesg.

One warning of possible significance is:
ACPI: No IRQ known for interrupt pin A of device 0000:00:11.1 - using IRQ 255
The 11.1 device is my IDE controller. Could this be an issue? I do not have 
any problems with disks ordinarily.

Please let me know if anything stands out.

Thanks

John
