Okay now I understand why I didn't find it. Thanks a lot!

But where is it called during boot process? Can't find it anywhere in /arch/x86 or init?

comment Triggering hardware interrupts by connecting parallel port pins 9 and 10 does not work
Yeah, I could do that but dump_stack() eventually just calls printk() too, right. But isn't e1000 already available in initrd? As I said it does not seem to be called after /dev/kmsg is created since otherwise I'd see it. I'll give dump_stack() a try.

Hmm, at least e1000_open() and thus e1000_irq_enable() gets called before /dev/kmsg is created, since the printk() I put into e1000_open() is not available in dmesg.

Thanks for the hint, should read properly.. m( Well, I did that but it didn't work. In detail I loaded the module insmod short and mknoded /dev/short0, after that I wrote binary junk to /dev/short0 by doing cat /sbin/* > /dev/short0 while I had pin 9 and 10 connected, but no interrupts occured.

Ok then this seems different with char devices. In the case of e1000 the module itself seems to enable irqs while booting.
