Because the kernel crashed in early stage of booting, there are no logs,
but I've written it from screen.

Here's what ksymoops says:

11: 8b 43 0c mov 0xc(%ebx),%eax
Kernel panic: Aiee, killing interrupt handler!

Hope that helps to find the bug, it's the first kernel in the 2.4 series
which doesn't boot.

Bye,

Manfred
