User mode accesses cause a SIGSEGV

[Prakash kanthi]

Hi Folk,

I have a problem with user mode processes on my PPC405
based board with 16MB SDRAM. I am using busybox based
'init'. When linux boots, init tries to swapn 'sh'.
Shell starts ok but after that, any 'application'
started under 'sh' bails out with error
"User mode accesses cause a SIGSEGV for <some
address>"

The address it bails out is always same and generally
is a huge value (ex: 0x92612077).

I am suspecting that there might be something wrong
with user mode PTEs. I am not sure when PTEs are
created how they are privileged.

Any help is appreciated.

Thanks,
Prakash
