SubjectKernel reboot on loading (port 0xEF)
Date
Hi once again.

Now I think I have found the reason that the kernel reboots itself on
loading.
It turnes out that the AMD Elan SC400 microcontroller has an alternative CPU
reset by
reading (yes reading) port 0xEF.
Does anyone know if linux reads this port and if so where should I look for
it.
BTW it has an alternative A20 gate control by reading port 0xEE but it
should be ORed with the other methods, so now in setup.S I have 3 methods
(to be safe :-) ).
