I'm really concerned that all those interrupts might slow down the
computer somehow...
Here is an attached syslog part after a reboot.
Sometimes, the ratelimit says that thousands of callbacks were suppressed.
Is there a way to make this message be displayed only once?
In arch/x86/kernel/irq.c, the line 213 is:
irq = __get_cpu_var(vector_irq)[vector];
In my case, the returned irq is -1. Doesn't it makes sense to not log
the "No irq handler for vector" message when irq< 0?
Or even a deeper answer: Why, in my case, the resulting irq is -1?
2009/8/10 Luis Fernando Planella Gonzalez<lfpg.dev@xxxxxxxxx>:I've just compiled 2.6.30.4, and it shows another info:
do_IRQ: 0.91 No irq handler for vector (irq -1)
Attached are the /proc/interrupts and the lspci -vv
Anyway, sorry for not specifying my hardware:
* Intel Core2 Duo 2.13 GHz
* 2GB RAM
* NVidia 7900 GS
Thanks.
