Description

This always happens when booting the 2.5.1 kernel I just compiled in normal
mode. It doesn't happen in safe mode. I can't get a kernel dump. It's a Dell
Latitude laptop.

History

#1 Updated by phma over 4 years ago

Booting with ACPI disabled succeeds, so it's something in the ACPI code.

Hi,

Is this still present? If so, I think we might need some more information, like
a dump or so.

Thanks,
Antonio Huete

It is still present, and I still can't get a dump. The trap happens before the
kernel turns dumping on.

Can you get a dump if you load the acpi module after you have booted the system
without it?

#5 Updated by phma almost 4 years ago

It doesn't crash. I'm not sure how to tell if acpi is doing anything.
