Hi,
Almu and I discovered that the following commit breaks --enable-apic
--enable-ncpus= >1 --disable-linux-groups
* d972c01c pmap: only map lower BIOS memory 1:1 when using Linux drivers
I believe the ACPI tables need temporary low memory mapping to access them.
Also, the commit:
* 54a4ca2
Applied, thanks!
