Hello –

 

I’m currently porting vmlinux from NEC’s = EMMA2L platform to EMMA2.  The problem I’m having is that linux = hangs when it attempts to do its first page fault: the page fault handler is = successfully called, the call to handle_mm_fault returns 2 (major fault)…but = then code execution appears to just stop.  Linux is not completely dead, = however – it still responds to a timer interrupt.

 

As the code for handling page faults is standard = code, and TLB hardware should be the same on EMMA2 as on EMMA2L (where it works!), = I don’t understand what’s gone wrong!  Does anyone have any = ideas?

 

Thanks for your help,
