That PC uses a Siemens D823 motherboard with dual Pentium 133 CPUs. According to lspci it has an Intel Corp. 82434LX [Mercury/Neptune] chipset. It's an ISA/EISA/PCI system with two IDE ports (RZ1000 chip), fd, serial, parallel, PS/2 onboard. I'm also using a PCI graphics card, an Adaptec AHA 2940 PCI SCSI controller, a 3c509 EISA NIC and an Adlib ISA sound card. The system is running Debian 3.0. PROBLEM: With 2.4.21 or 2.4.22-rc1 (both with and without SMP support included) the system on startup does not find an IRQ for the floppy controller, and when it comes to probing the IDE disks I get "irq probe failed" and later "lost interrupt". If I boot with "noapic" kernel command line option things do work. If there's any more info I can provide (kernel configs maybe?) or things I could test please do not hesitste to let me know. I'd appreciate your feedback. Georg PS: additional Info (output from 2.4.20 dmsg; might help you?) Please note the "IO-APIC (apicid-pin) 2-0 not connected" line. Maybe that's the issue?
