    Subjectirq 12: nobody cared! (2.6.0-test6)
    This is Linux 2.6.0-test6 on a PC with VIA KT133A chipset (MSI MS-6330
    mainboard), PS/2 keyboard, USB mouse. In test5 it hung on boot just
    after printing
    mice: PS/2 mouse device common for all mice
    input: PC Speaker

    In 2.6.0-test6, it spits out several "irq 12: nobody cared!" messages
    with backtraces and then continues as if nothing happened. The system
    works fine, PS/2 keyboard and USB mouse both work too. Similar
    configuration (PS/2 keyboard + USB mouse) works fine on an i815 chipset
    computer.

    Linux version 2.6.0-test6 (mroos@vaarikas) (gcc version 3.3.2 20030908 (Debian prerelease)) #15 Sun Sep 28 13:06:21 EEST 2003
