If I try too boot a kernel build from NetBSD-current sources from 2006-07-03
or newer my system panics early during system startup with this message:
BIOS32 rev. 0 found at 0xf0010
panic: x86_mem_add_mapping: overflow
The stack trace looks like this:
I don't have a crash dump because the machine dies before it starts
looking for disks.
I tried two standard kernel configurations afterwards:
1.) "GENERIC" (which doesn't include any ACPI support) works fine.
2.) "GENERIC.MPACPI" dies after a NULL pointer access in the function
AcpiTbVerifyTableChecksum(). Hisashi T Fujinaka reported a
similar problem on the "current-users" mailing list.
Build the "GENERIC.MPACPI" kernel and boot it.
