I am trying to get the 2.4 kernel up and running on the Cobalt boxes. At the moment I am trying to get the initial transition from kernel to user mode working. The elf loader is trying to put stuff in the stack for the new user process and *each* call to NEW_AUX_ENTRY is generating a page fault that cannot be resolved. The address generated by the BadVAddr on the TLBS exception is not correct. Also, I never receive a TLBrefill exception on the accesses. It is using the except_vec0_nevada handler. All that I can think of is that the handler at 0x80000000 is getting smashed after it is copied in -- ala troubles with _kd_mksound last year. Any ideas on what is happening?? how to fix it??
