> Hmm, so that's fine. What pointer is returned by madt_map_table?
0x800e7610
I also put some prints in afterwards to try and see how far through
the loop it was getting:
count = (xsdt->Header.Length - sizeof(ACPI_TABLE_HEADER)) /
sizeof(UINT64);
printf("DEBUG: count is %d\n", count);
for (i = 0; i < count; i++) {
printf("DEBUG: probing %d - offset %p\n",
i, xsdt->TableOffsetEntry[i]);
if (madt_probe_table(xsdt->TableOffsetEntry[i]))
break;
}
The output is interesting - I get count printed as 6, but then nothing
else, just the panic. Which leads me to believe that it is the access
to xsdt->TableOffsetEntry[0] which is causing the panic.
