I have a Pentium III 933/133 (Coppermine, stepping 6) in an Intel-manufactured i810 motherboard (hey, I know it's a lame chipset, but it was on sale). On boot, the kernel (version 2.4.6-pre8) identifies and maps the IO-APIC onboard, but does not assign any IRQs to it. The relevant boot log snippet follows. [root@fortytwo i386]# cat /var/log/dmesg ... ... mapped APIC to ffffe000 (0121c000) Kernel command line: auto BOOT_IMAGE=linux-test ro root=307 BOOT_FILE=/boot/vmlinuz-2.4.6-pre8 devfs=mount pirq=9,4 PIRQ redirection, working around broken MP-BIOS. ... PIRQ0 -> IRQ 9 ... PIRQ1 -> IRQ 4 ... ... And /proc/interrupts: [root@fortytwo i386]# cat /proc/interrupts CPU0 0: 79409 XT-PIC timer 1: 5911 XT-PIC keyboard 2: 0 XT-PIC cascade 4: 990 XT-PIC es1371 8: 1 XT-PIC rtc 9: 26402 XT-PIC usb-uhci, serial 11: 16473 XT-PIC i810@PCI:0:1:0 14: 5152 XT-PIC ide0 15: 47 XT-PIC ide1 NMI: 0 ERR: 0 MIS: 0 [root@fortytwo i386]# This problem also occurs when booting without the pirq switch. I've configured everything the way it's mentioned in Documentation/i386/IO-APIC.txt, but it doesn't help. Anyway, thx in advance for the help. -- Colin ------------------------------------------------------------ The CompNerd Network: http://www.compnerd.com/ Where a nerd can be a nerd.
