Unable to load image \SystemRoot\system32\DRIVERS\atikmdag.sys, Win32 error 0n2

*** WARNING: Unable to verify timestamp for atikmdag.sys

*** ERROR: Module load completed but symbols could not be loaded for atikmdag.sys

Probably caused by : dxgkrnl.sys ( dxgkrnl!TdrTimedOperationBugcheckOnTimeout+37 )

The device driver is spinning in an infinite loop, most likely waiting for

hardware to become idle. This usually indicates problem with the hardware

itself or with the device driver programming the hardware incorrectly.

If the kernel debugger is connected and running when watchdog detects a

timeout condition then DbgBreakPoint() will be called instead of KeBugCheckEx()

and detailed message including bugcheck arguments will be printed to the

debugger. This way we can identify an offending thread, set breakpoints in it,

and hit go to return to the spinning code to debug it further. Because

KeBugCheckEx() is not called the .bugcheck directive will not return bugcheck

information in this case. The arguments are already printed out to the kernel

debugger. You can also retrieve them from a global variable via

"dd watchdog!g_WdBugCheckData l5" (use dq on NT64).

On MP machines it is possible to hit a timeout when the spinning thread is

interrupted by hardware interrupt and ISR or DPC routine is running at the time

of the bugcheck (this is because the timeout's work item can be delivered and

handled on the second CPU and the same time). If this is the case you will have

to look deeper at the offending thread's stack (e.g. using dds) to determine

spinning code which caused the timeout to occur.
