A Crash Occurs in Ks.sys on Computers with Intel Hyper-Threading CPU (812035)


The information in this article applies to:

  • Microsoft Windows XP Professional SP1
  • Microsoft Windows XP Home Edition SP1

SYMPTOMS

Ks.sys may crash if you repeatedly start and stop a Hauppauge playback graph on a computer with an Intel CPU that uses Hyper-Threading technology.

CAUSE

I/O request packets (IRPs) are completed on the pending queues without being called back. The routine does not undo the preparation for the request. That causes resources to leak. The data buffer address for data SRBs is not restored to the correct address from the mapped address. Therefore, the FreeFrame routine calls the wrong address when the frames are freed from the allocator.
