hi all, I recently ported the linux kernel v 2.4.11-pre5 to MDPPro ( MPC860T processor ) board..the kernel dies with an Oops and everytime at a different place....
i use ppcboot to load the kernel...
i am attaching a sample message below....
upon back tracing i found that at some point the kernel tries to execute code in Letext ( according to System.map)....
it'd be great if someone can explain me what this Letext is and why is the control going there???
thanx in advance _kalyan.
