Re: kern/35899 (uvm_fault in pmap_activate() called from uvm_proc_exit())



Synopsis: uvm_fault in pmap_activate() called from uvm_proc_exit()

State-Changed-From-To: open->feedback
State-Changed-By: rmind%NetBSD.org@localhost
State-Changed-When: Sun, 14 Jun 2009 21:54:48 +0000
State-Changed-Why:
Since pmap value is 0xdeadbeef, it crashes here in pmap_activate():
        pcb->pcb_ldt_sel = pmap->pm_ldt_sel;
It is odd, because uvm_proc_exit() sets proc0 vmspace which is pmap_kernel().
Anyway, semantics has changed in 5.0/-current. Can you still reproduce this?
