WinDbg: Unable to get verifier list


Y

Yousuf Khan

I've been attempting to get to the bottom of a recurring BSOD crash
happening on my system. I've already had 4 crashes so far over the past
two weeks. So I've identified that NTOSKRNL.EXE is involved in all of
them so far. It always somewhere in the stack. So I enabled Driver
Verifier on NTOSKRNL, as well as HAL.DLL, NTFS.SYS, and FLTMGR.SYS which
were also identified on the stack during various of the events.

Okay so I had my latest crash yesterday, and it occurred on NTOSKRNL as
well. The Verifier was already enabled on the system prior to this
crash, and then when go to Windbg and execute the "!verifier" command,
it comes back with the message, "Unable to get verifier list". Why not,
it should be enabled?

When I check them on the command-prompt I get the following output back,
and they confirm that all of the files are being monitored. So can
somebody familiar with Driver Verifier and Windbg help me out here?
