Possible that this has to do with the other thing? ] ] This is a pretty good indication that something is mis-confugred. IRQ 7 ] is the 'junk' interrupt, which means it gets all of the interrupts not ] otherwise assigned to a particular piece of hardware. Something is ] generating interrupts on your system bogusly and you need to find out ] what. That means the interrupt that happens is not guaranteed to be IRQ 7 but maybe any other unassigned interrupt? The only cards I have installed in this machine are the following: IDE/FDC controller card (without any other ports etc) Multi I/O card with COM1 COM2 LPT(completely disabled including IRQ) and Gameport (also disabled) Dual I/O card with COM3 and COM4 standard ET4000 video board Ethernet adaptor (ISA 16 bit software configurable) ---- The kernel seems to find all those devices: FreeBSD 2.2-CURRENT #2: Mon Mar 25 15:46:17 MET 1996 root@deadline.snafu.de:/usr/src/sys/compile/CENOTAPH CPU: i486DX (486-class CPU) real memory = 4456448 (4352K bytes) avail memory = 3133440 (3060K bytes) Probing for devices on the ISA bus: sc0 at 0x60-0x6f irq 1 on motherboard sc0: VGA mono <4 virtual consoles, flags=0x0> ed0 at 0x300-0x31f irq 12 on isa ed0: address 08:00:00:19:08:36, type NE2000 (16 bit) sio0 at 0x3f8-0x3ff irq 4 on isa sio0: type 16450 sio1 at 0x2f8-0x2ff irq 3 on isa sio1: type 16550A sio2 at 0x3e8-0x3ef irq 9 on isa sio2: type 16550A sio3 at 0x2e8-0x2ef irq 5 on isa sio3: type 16550A lpt0 not found at 0x278 wdc0 at 0x1f0-0x1f7 irq 14 flags 0x80ff80ff on isa wdc0: unit 0 (wd0): , multi-block-64 wd0: 202MB (415264 sectors), 683 cyls, 16 heads, 38 S/T, 512 B/S fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa fdc0: NEC 765 fd0: 1.44MB 3.5in 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 That's what it goes like.
