This is for NetBSD on MIPS processor, but answer for Linux is also welcome.

I see that an interrupt occurred while receiving a network packet. This hardware interrupt sees a TLB miss on store operation and kernel crashed. When I see the core-dump, gdb points to LWP of a process (lets say ProcA).

I am assuming that, this hardware interrupt may have preempted the ProcA and started execution on ProcA's kernel stack. Though in the stack frame I don't see anything from ProcA, what I don't understand is why gdb still points to ProcA.

ultimate cause
