Windows 7: BSOD driver verifier error 0x000000c9 IO Manager Violation

Windows 7 Professional 64-bit SP1
BSOD driver verifier error 0x000000c9 IO Manager Violation

I began having startup problems leading to a BSOD. When I ran driver verifier, It repeatedly crashed upon reboot and I had to disable verifier in safe mode to boot. The error seemed to be with ntsokrnlpa.exe and HIDCLASS.sys This was after a reinstall (W7 Pro x86 w/ SP1) Stop code: 0x000000c9 (0x00000220, 0x9237FA8C, 0x9B13CE00, 0x8AD70030) The IO Manager has detected a violation by a driver that is being verified. The faulty driver that is being verified must be debugged and replaced with a working version: Dump files attached. Thanks for your help!
