Hi,

here is the output of the dmesg command after some time using a new kernel
(2.4.19) supporting IO-APIC... note the last few lines saying 'APIC
error...'.
dotconfig.bz2 is the .config of the kernel after the 'make menuconfig'.

Which other information do you need? I'd like to help kernel development.

[]'s
