[Barrelfish-users] skb problems booting on x86_32: can't find Eclipse?

Wed Jul 24 10:12:59 CEST 2013

Hi Malte,

I'd suggest to turn on (in addition to Manuel's suggestion) debugging
for the acpi subsystem if you want to follow up on the 32bit issue.
This can be done in usr/acpi/acpi_debug.h by uncommenting the line
that defines ACPI_SERVICE_DEBUG.

For the x86_64 issue my best suggestion right now is to add a printf
in mm_realloc_range (lib/mm/mm.c:661) to see what arguments are given
to the function. The only places where this function is called are in
the acpi subsystem so I would leave ACPI_SERVICE_DEBUG on for this as
well.

Cheers,
-- Simon
