Hi Eric
I was trying to boot(through grub) to a relocatable kernel on an EM64T
machine but I end up in an OOPS: 'Unable to handle kernel paging request'.
I am using 2.6.18-rc4 kernel, applied your 33 patches for relocatable kernel
support along with Don Zickus' patch which dealt with the setting of the
_PAGE_NX bit.
Is there something obvious which I am missing here?
Attaching along the complete boot log. I dont see the entire OOPs trace also
in the log though...I shall continue looking into this to get more clues.
The patches worked fine when tested on an i386 machine.
Thanks
Rachita
