Hello, I am now running 4.0-STABLE for a week. I now have periodically in my logs : stray irq 7 stray irq 7 stray irq 7 stray irq 7 stray irq 7 too many stray irq 7's; not logging any more Before I was running 3-STABLE for a year without any message of this kind. The irq #7 doesn't seem to be used by my system. Looking in /usr/src/sys/i386/isa/intr_machdep.c : * Well the reason you got bursts of intr #7 is because someone * raised an interrupt line and dropped it before the 8259 could * prioritize it. This is documented in the intel data book. * This means you have BAD hardware! I have changed this so * that only the first 5 get logged, then it quits logging them, * and puts out a special message. rgrimes 3/25/1993 Is this still correct? Should I care about it? Bad hardware? The source then mentions : /* * XXX TODO print a different message for #7 if it is * for a glitch. Glitches can be distinguished from * real #7's by testing that the in-service bit is _not_ * set. The test must be done before sending an EOI so * it can't be done if we are using AUTO_EOI_1. */ but this is far too complicated for me :-) I am running : FreeBSD mychkine.crans.ens-cachan.fr 4.0-STABLE FreeBSD 4.0-STABLE #23: Sun Mar 19 22:51:34 CET 2000 root@mychkine.crans.ens-cachan.fr:/usr/src/sys/compile/mychkine i386 on a Dell Latitude CPi.
