Turns out that it isn't - it's in the other branch of the if using the
RSDT instead of the XSDT. Not sure why the debugger was giving
misleading information. I added prints to find out which path it was
taking and to print out some values after the line
"rsdt = madt_map_table(rsdp->RsdtPhysicalAddress, 1, ACPI_SIG_RSDT);"
The value of rsdtl is 0x800e7610, but the value of rsdp->XsdtPhysicalAddress
is zero! So I guess that is where the panic is comming from. So where
now ? Is there an equivalent patch to the one you emailed
earlier for this branch of the if ?
I wont have access to the machine over the weekend, but I can make more tests
on monday morning.
thanks for the help,
-pete.
