[bedevtalk] IRQ 16 ???

[Oliver Tappe]

Hi there,

a couple of months ago, I bought a new machine with a Pentium 4 920 and put 
BeOS R5 on it. Everything works basically (esp. after I have installed 
Michael Lotz's cpu_fix), but the system dumps seemingly strange output to 
syslog:

	KERN 'idle thread 2'[2]: disable irq 16
	KERN 'idle thread 2'[2]: irq 16 reenabled (handled by 0x60054cf0)
	KERN 'idle thread 2'[2]: disable irq 16
	KERN 'TrackerTaskLoop'[103]: irq 16 reenabled (handled by 0x60054cf0)
	KERN 'TrackerTaskLoop'[103]: disable irq 16
	KERN 'idle thread 1'[1]: irq 16 reenabled (handled by 0x60054cf0)
	KERN 'TrackerTaskLoop'[103]: disable irq 16
	KERN 'TrackerTaskLoop'[103]: irq 16 reenabled (handled by 0x60054cf0)
	KERN 'TrackerTaskLoop'[103]: disable irq 16
	KERN 'idle thread 2'[2]: irq 16 reenabled (handled by 0x60054cf0)
	KERN 'TrackerTaskLoop'[103]: disable irq 16
	KERN 'idle thread 1'[1]: irq 16 reenabled (handled by 0x60054cf0)
	KERN 'idle thread 1'[1]: disable irq 16
	KERN 'idle thread 2'[2]: irq 16 reenabled (handled by 0x60054cf0)
	KERN 'idle thread 2'[2]: disable irq 16
	KERN 'idle thread 2'[2]: irq 16 reenabled (handled by 0x60054cf0)

I have tried fiddling with the BIOS settings, deactivating one of the cores, 
but these message still come in (at a worrying speed, I might add: the system 
is shifting from syslog to syslog_old every two minutes!).

Has anyone listening here ever seen this kind of stuff? What the bleep is IRQ 
16 anyway? I thought there were only IRQs from 1-15?

I don't know whether or not it's related, but after the system has run for 
one or two hours the (Open-)Tracker Taskloop starts eating considerable 
CPU-cycles althought there's nothing to do...

Any info or educated guesses would be very appreciated >:o)

cheers,
