Description

I am running 3.1-DEVELOPMENT DragonFly v3.1.0.1479.g71fdcb3-DEVELOPMENT and I got about 7 panics of this kind in the last 10 days. They happen independent of daytime (so I think stuff like hammer cleanup is not the problem). I attached a listing of my /var/crash at the bottom. Dumps available if needed.

History

#1 Updated by vsrinivas over 1 year ago

I have a number of cores for this panic available also.

1) The page in question is always 0xc0f70000.
2) In all the cores I have and in one of the cores discussed on IRC, when you look at the backtrace, the faultstate structure when viewed in vm_fault()'s frame refers to a busy, reasonable page in the kernel_map. (Reasonable for this access anyway, though why it is faulting on a kernel address to begin with, I am not sure). In the vm_fault_object frame, the faultstate structure refers to an unreasonable/uninitialized page.
