DRIVER_STATE_POWER_FAILURE 0x9F, no crash dump written. Typical?
Some background first:
I have a Windows 7 SP1 x64 computer. My pagefile is disabled. I enabled DedicatedDumpFile and DumpFile locations on a different hard drive (because the C drive that holds windows is an SSD drive with limited space). I also enabled the user generated crash option to test this setup:
After rebooting the test succeeded and I was able to manually cause a kernel dump (CrashDumpEnabled = 0x2) to be written to disk by holding down the right CTRL key while hitting Scroll Lock twice.Code:[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\kbdhid\Parameters] "CrashOnCtrlScroll"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\i8042prt\Parameters] "CrashOnCtrlScroll"=dword:00000001
Now I did all of this to catch DRIVER_STATE_POWER_FAILURE on hibernate. It's extremely rare on my system but when it has happened there was no record left of it happening in event viewer or seemingly anywhere because I assume crash dumps were disabled (windows does this automatically when there is no pagefile). Now that the crash dumps are explicitly enabled I had another DRIVER_STATE_POWER_FAILURE today but again nothing was written. I suspect my VMWare Workstation 7 drivers, only because every time it's happened I've had some virtual machine running. That may be a coincidence though.
So is it typical for DRIVER_STATE_POWER_FAILURE to have no dump file? I'm wondering if since the computer was in the process of hibernating maybe it already shut power to the SATA drive that I write the crash dumps to, and that's why the dump couldn't be written. Or maybe that makes no sense. I really don't know.
I welcome any insight anyone has on this issue. Thanks
