Hi all. I'm trying to get the Kernel Streaming extension ks.dll working in
Windbg - Specifically the !ks.dumplog feature.
WDK: 8.1
Target: Windows 8 Kernel Version 9600 MP (1 procs) Checked x64
Host: Win7, windbg:6.3.9600.16384 AMD64
1: kd> !ks.dumplog
---> INITIALIZING KS DEBUGGER EXTENSION
---> This will only happen once... please wait...
---> Checking KS symbols... please wait...
---> KS symbols seem ok...
---> Initializing all LibExt modules...
---> This may take a few moments as symbols / modules are validated
---> Please wait...
---> LibExt modules initialized and validated
Matched: fffff800`01c24198 ks!KsLog = <no type information>

Cannot access the log; ensure you are running debug ks.sys!
Executing this command shows mass quantities of ks.sys symbol output which
certainly looks debug-ish:

Any ideas on what might be wrong / missing?
Thanks very much,
Wade.
