Hello gurus,

After I had fixed booting of uniprocessor kernel on my crappy hw, I've
tried to boot MP kernel and it crashed at isa_intr_establish()
[in this case acpi driver is left disabled]:

So I've done some debugging on it and have figured out some details.
"no isa bus" panic happens when mp_isa_bus is NULL. This
can happen if only mpbios_bus() is not called with the
appropriate argument (and actually it doesn't get called at all).
So if it isn't called it means that mpbios_scan() doesn't come across
the MPS_MCT_BUS case.

So I've put a bunch of printfs in mpbios_scan() and mpbios_search()
to understand what stands behind this. It turned out that
the mpbios code finds a MP Configuration Table with only one
entry of zero type (the CPU). So it configures cpu0. No ioapics and
no busses.

In my case this code gets called in order to find and map the MP
Floating Pointer Structure:

mp_fps = mpbios_search(self, BIOS_BASE, BIOS_COUNT, &mp_fp_map);

I've reprogrammed the mpbios_search logic to do a complete search
up to the end and print out search results. This got me nowhere.
There was only one match which was used before.

So my question is: is there any other address space to search for
the MP Floating Pointer Structure?

Maybe you can suggest me something to try or find out?

Thanks.


As a side note: I've also tried acpi-enabled kernel. In this case
kernel finds cpu0 & cpu1, ioapic, and crashes in AML parser trying
to figure out the PCI buses... The dmesg:
