I’m trying to analyze a memory dump but I keep getting mismatched errors on my pdb and sys files. I have been unable to reproduce the error since I figured out what I’m doing here. The pdb and sys files should be the same except a version number and timestamp. Is there a way to force windbg to ignore the time/version? I want to get a line number or something to find the previously faulty instruction. If it does indeed provide line numbers for the driver code. Anything to determine which call to READ_REGISTER_ULONG was the culprit. Any ideas on how to use the dump to get a line number without the time matched pdb or sys file?
.symopt+ 0x40
If you really want to hack away, you can resort to explicitly loading each pdb:
.reload -f =
That being said, it’s likely that you just don’t have your symbols setup correctly; fixing this would be a good idea, and either way, the using mismatched symbols is at best a last resort.
How about you post the output of these commands and let’s see what’s going on?
.symopt+0x80000000
.reload -f -n
lml
lme
mm
What does the base address refer to?
Here is an abbreviated version. I removed most of the files that reported no problems. When I enable noisy I see it looking n the right places eventually but gives mismatch errors. I assume this is because I have recompiled the driver since the crash. Since I can’t reproduce the crash my pdb file has a new timestamp. I made no code changes outside of changing the version number.

Well, if you can’t reproduce the symbol files, then indeed a forced load is your only option, though it maybe worse than nothing if your symbols really don’t match your binary in any way beyond the signature (windbg uses internal signatures not timestamps to match binaries to symbols).
I know that you said that you don’t think you changed anything in the code, but mismatch(es) could also be caused by changes to the build settings (compiler/linker options) and/or using different versions of the toolchain. So, if you do this, the first thing that you need to do is obviously conduct some sanity checks to get a handle on whether this is the case or not. As there’s really no good way to ‘verify’ that all is well, if you see anything that looks incorrect, I’d not use the symbols.
The base address means the address where a module is loaded. Using ‘RTKVHDA’ as an example, to force load its symbols, you would use something like:
.reload -f RTKVHDA.sys=92425000
Good luck,

I ran .symopt+0x40
and then analyze and that worked. I actually got the correct line of code.
I tried to force reload my sys file but it won’t do it claiming my pdb file is mismatched.
My bad - I forgot the ‘-i’ option on the ‘.reload’ command line.
Good luck,
mm
Thanks. Adding -i also works.
