Module load completed but symbols could not be loaded

WINDBG
1

Greetings,

I am debugging a driver in the primitive state using windbg with 2
systems. Initially, I
had some problems getting symbols loaded and breakpoints set, but it
seemed to resolve
itself somehow. The error I am now consistently getting is below:

Symbol search path is:
C:\WINDDK\2600.1106\src\network\ndis\softair\51\objchk_wxp_x86\i386;c:\symbols

*** ERROR: Module load completed but symbols could not be loaded for
softair.sys

I have softair.sys and softair.pdb in the c:\symbols directory as
evidenced by:

C:\WINDDK\2600~1.110\src\network\ndis\softair>dir c:\symbols
Volume in drive C has no label.
Volume Serial Number is 8401-7D77

The 'lm' command shows softair.sys in the unloaded modules section,
which is what I
have come to expect. I can cause it to be loaded by running install on
the target, but now
the symbols refuse to load.

Help appreciated.

It could be that the symbols don’t match what is running on the system.

Do:
!sym noisy
.reload

And you’ll get more info about why the symbol load is failing.

I’m sure you are doing this already, but it is always worth reminding to
make sure you are using the latest version of the debugger. See

Thank you! I feel a bit foolish. I introduced a bug into my target-update
process
which left me in this mismatched state.

Much obliged.
