Code:
BugCheck D1, {538, 2, 0, fffff880040a6836}
This bugcheck indicates a driver attempted to access a pageable memory address when the IRQL was too high (2), to access pageable memory the IRQL must be at 1 or below. In this case, even if the IRQL was below 2 it would still bugcheck, given that A page fault which is what occurs when invalid memory is referenced in pageable memory isn't allowed to happen about IRQL 1 and it's an invalid address, I believe the starting address for user mode is something like 0x00010000 anything below is reserved so accessing it is not allowed.

Your network driver is causing the problems, it's out of date, update it here.
Drivers for Atheros AR928X and Windows 7
Information
This driver is for an Atheros AR928X wireless network card on Windows 7 64bit systems.
Code:
BugCheck 9F, {3, fffffa8003bd9060, fffff80000b9c4d8, fffffa800486cc10}
Probably caused by : pci.sys
pci.sys is the driver located at the bottom of the PDO stack which is where the IRP is passed down to.
It's also blocking an IRP longer than it should.
Code:
0: kd> !irp fffffa800486cc10
Irp is active with 5 stacks 3 is current (= 0xfffffa800486cd70)
No Mdl: No System Buffer: Thread 00000000: Irp stack trace.
