Re: [microblaze-uclinux] Bad page state in process 'swapper'

Cor,

Let me be more precise.  My Suzaku SZ130 board runs fine with the Suzaku 
flavor of uClinux which looks to be a branch that is about two years 
old.   I wasn't able to get the Petalinux 2.4 uClinux kernel running on 
the Suzaku, but I only did a single attempt and didn't try to debug it 
since I'm more interested in the 2.6 kernel if I'm going to port 
Petalinux to it.
