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.
