Rum, you aren't running that patch I emailed you last time (which has
since gone into the tree). I verified it by disassembling vm_waitproc():
0xc02c81bc <vm_waitproc>: push %ebp
0xc02c81bd <vm_waitproc+1>: mov %esp,%ebp
0xc02c81bf <vm_waitproc+3>: push %ebx
0xc02c81c0 <vm_waitproc+4>: mov 0x8(%ebp),%ebx
0xc02c81c3 <vm_waitproc+7>: push %ebx
0xc02c81c4 <vm_waitproc+8>: call 0xc0362bec <cpu_proc_wait>
0xc02c81c9 <vm_waitproc+13>: push %ebx
0xc02c81ca <vm_waitproc+14>: call 0xc02c90a0 <vmspace_exitfree>
0xc02c81cf <vm_waitproc+19>: mov 0xfffffffc(%ebp),%ebx
0xc02c81d2 <vm_waitproc+22>: leave
0xc02c81d3 <vm_waitproc+23>: ret
There should be a 'movl $0x0,0x1c(%ebx)' in there that corresponds
to the 'p->p_stats = NULL' line that was added to vm_waitproc() in
vm/vm_glue.c 1.28, and there isn't.
I recommend upgrading to DragonFly_Stable. It has that patch plus a
number of other bugs fixes.
