I've hacked up the sysrq code so that it gives me another command : j ,
which dumps the current IRQ status on the console :

SysRq : Show IRQ status
......
Showing info for IRQ 14
status :
depth : 0
wake_depth : 0
irq_count : 38717
irqs_unhandled : 0

Showing info for IRQ 15
status : DISABLED
depth : 1
wake_depth : 0
irq_count : 22
irqs_unhandled : 0

which is a the (incomplete) result on my machine after loading a module
that does disable_irq(15) on module load.

I've put the patch at http://www.jdi-ict.nl/areca/sysrq-j.patch
I'll do a follow-up when anything usefull comes out.


Regards,


Igmar
