I know "stray irqs" from when hardware is "disabled" or you have hardware in the machine the OS doesn't support and thus doesn't register drivers or resources for. That's when the events end up in the "stray" (i.e. "unexpected since not caused by me") handler. Sound cards were known to cause this some five to eight years ago. Some irq7 got triggered "by chance" without the lpt driver thinking it has done it or some such. And I've seem machines with crackling sound in the speaker boxes whenever print jobs via lpt were executed. It must have been some kind of cross over noise, maybe not enough or defective separation of electrical paths or something. virtually yours 82D1 9B9C 01DC 4FB4 D7B4 61BE 3F49 4F77 72DE DA76 Gerhard Sittig true | mail -s "get gpg key" Gerhard.Sittig@gmx.net -- If you don't understand or are scared by any of the above ask your parents or an adult to help you.
