This is a stack trace (backtrace) where all finctions are removed and only modules are left. Useful for depicting component dependencies. Here is an example:

0: kd> kc 100
nt!KiSwapContext
nt!KiSwapThread
nt!KeDelayExecutionThread
3rdPartyAVDriver
3rdPartyAVDriver
3rdPartyAVDriver
3rdPartyAVDriver
nt!IofCallDriver
DriverA!Dispatch
DriverA!KUI_dispatch
nt!IofCallDriver
DriverB!PassThrough
DriverB!Dispatch
nt!IofCallDriver
DriverC!LowerPassThrough
DriverC

DriverC
DriverC!DispatchPassThrough
nt!IofCallDriver
nt!IopParseDevice
nt!ObpLookupObjectName
nt!ObOpenObjectByName
nt!IopCreateFile
nt!IoCreateFile
nt!NtOpenFile
nt!KiFastCallEntry
ntdll!KiFastSystemCallRet
ntdll!NtOpenFile
ntdll!LdrpCreateDllSection
ntdll!LdrpMapDll
ntdll!LdrpLoadDll
ntdll!LdrLoadDll
kernel32!LoadLibraryExW
kernel32!LoadLibraryW
ntdll!LdrpCallInitRoutine
ntdll!LdrpRunInitializeRoutines
ntdll!LdrpLoadDll
ntdll!LdrLoadDll
kernel32!LoadLibraryExW
kernel32!LoadLibraryW
USER32!LoadAppDlls
USER32!ClientThreadSetup
USER32!__ClientThreadSetup
ntdll!KiUserCallbackDispatcher
nt!KiCallUserMode
nt!KeUserModeCallback
win32k!xxxClientThreadSetup
win32k!xxxCreateThreadInfo
win32k!UserThreadCallout
win32k!W32pThreadCallout
nt!PsConvertToGuiThread
nt!KiBBTUnexpectedRange

Collapsed stack trace is much simpler to grasp: 

nt

nt
DriverA
nt
DriverB
nt
DriverC
nt
ntdll
kernel32
ntdll
kernel32
USER32
ntdll
