I've installed an additional isa multi adapter (with 2 COM ports, 1 Parallel, 1 floppy, 1 HDD) and disabled onboard COMs and Parallel ports on my box. The kernel message (stray irq 7) don't appear in the system and I have both RS232 (the modem and the mouse works fine). I suppose my onboard COMs and Parallel ports are dead. But it's very bad diagnostic message - "stray irq 7" - for this trouble that appeared even when I disabled onboard COMs and Parallel ports in BIOS, but didn't install multi adapter. I even removed all drivers for COMs and parallel ports from the kernel, but this message wasn't lost. I understand this is a hardware problem, but this message appear not only on my box. The friend of mine said my that he see same kernel message on his home box every day but it don't affect on his work and his COMs ports work fine. Does anyone have any comments?
