:RC2 doesn't boot on my T42p. It crashes (Page fault, Trap 12) after loading
:kernel, leaving critical section and enabling interrupts :(.
:This also happens with acpi disabled.

:Any hints how to debug this crash? I have no serial in my laptop :(

:Best Regards,
It sounds like you got a DDB> prompt, so what you need to do is
write down the register information starting at the 'Page fault' line,
e.g.:
Fatal trap 12: page fault while in kernel mode
fault virtual address = ...
fault code = ...
instruction pointer =
stack pointer =
frame pointer =
code segment =
=
processor eflags =
current process =
current thread =
interrupt mask = ...
panic: from debugger
Then, at the DDB> line you need to type 'trace' and write down the
procedural backtrace. The most important information are the procedure
names and the instruction offset at the end of each line.
