![]() ![]() The most two most important functions are PopCheckIrpWatchdog and PopCheckForIdleness. ![]() Unfortunately, I don’t have original dump file anymore. If we examine the stack of a Stop 0x9F, we can notice a few interesting functions. Windows monitors this activity with the use of timer dispatcher objects. Stop 0x9Fs are largely caused by a device driver which isn’t passing the power IRP through its driver stack to appropriate drivers which are able to process the power IRP. It’s important to remember that filter and bus drivers are commonly blamed with these bugchecks, because these drivers tend to be the only drivers which will handle the actual power IRP. This bugcheck is almost always exclusively related to device drivers not handling power IRPs correctly. The Stop 0x9F commonly refers to the system being in a inconsistent or unsupported power state. Please also note that I may use different dump files since I can’t find the original dump file I used originally. As a result, I’ve decided to post much of the original content again with the addition of the commands.įurther to the above, I feel that the guide should have originally been posted as a WordPress post because of the improved readability and search engine indexing etc. Since then, there has been a number of different WinDbg commands and/or extensions, which I’ve learned about which could prove useful when debugging this bugcheck. ![]() ![]() Note: I originally wrote about this bugcheck on this site several years ago now, however, the original guide was written in a Word document which was attached to the post. ![]()
