kid sister to read then don't post it. No flame wars, no abusive conduct, no programming
questions and please don't post ads.
1. The lounge is for the CodeProject community to discuss things of interest to the community, and as a place for the whole community to participate. It is, first and foremost, a respectful meeting and discussion area for those wishing to discuss the life of a Software developer.
The #1 rule is: Be respectful of others, of the site, and of the community as a whole.
2. Technical discussions are welcome, but if you need specific programming question answered please use Quick Answers[^], or to discussion your programming problem in depth use the programming forums[^]. We encourage technical discussion, but this is a general discussion forum, not a programming Q&A forum. Posts will be moved or deleted if they fit better elsewhere.
4. No politics (including enviro-politics[^]), no sex, no religion. This is a community for software development. There are plenty of other sites that are far more appropriate for these discussions. Or if you must, use the Back Room[^] - but enter at your own risk.
5. Nothing Not Safe For Work, nothing you would not want your wife/husband, your girlfriend/boyfriend, your mother or your kid sister seeing on your screen. For those discussions where you wish to be a little more frank, use the Soapbox[^]
6. Any personal attacks, any spam, any advertising, any trolling, or any abuse of the rules will result in your account being removed.
7. Not everyone's first language is English. Be understanding.
Please respect the community and respect each other. We are of many cultures so remember that. Don't assume others understand you are joking, don't belittle anyone for taking offense or being thin skinned.
We are a community for software developers. Leave the egos at the door.
I was using my laptop then took a break for lunch.
Came back and it had restarted.
I checked Windows Updates and it said there was one installed successfully on 02/13.
Why did my computer suddenly restart?
I looked in Event Log (System):
The previous system shutdown at 12:19:13 PM on 2/17/2018 was unexpected.
Next I find this:
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. (Source is Kernel-Power)
It's a laptop so has battery backup, so probably not a loss of power.
Here's another weird one (not sure what bugcheck is):
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000009f (0x0000000000000003, 0xffffd4095cacd830, 0xffffee8039c5ac40, 0xffffd40965c8ebd0). A dump was saved in: C:\WINDOWS\MEMORY.DMP. Report Id: 8d730435-e93f-4b3c-8ffa-bfafe4115fec.
Right before the restart I see:
The local adapter does not support an important Low Energy controller state to support peripheral mode. The minimum required supported state mask is 0x491f7fffff, got 0x1fffffff. Low Energy peripheral role functionality will not be available.
Maybe it went low power, then the device didn't support it so the system crashed? I don't know.
I did find one in the Event Log (Application) that occurred right before the reboot time:
Application Event Log:
SettingSyncHost (11192,G,0) The beta feature EseDiskFlushConsistency is enabled in ESENT due to the beta site mode settings 0x800000.
Apparently that is a BETA Win 10 1709 feature.
I'm wondering if this was the same restart problem @chris-maunder (and others) experienced the other day (Windows Update,No Thanks - Lounge[^]). Was their's an actual update or this same problem / crash? If I had ignored this I would've just thought it was a Rogue Update.
If you had gone one more entry in the log, you'd see this:
"Windows 10 was detected. The system is inherently unstable."
".45 ACP - because shooting twice is just silly" - JSOP, 2010 ----- You can never have too much ammo - unless you're swimming, or on fire. - JSOP, 2010 ----- When you pry the gun from my cold dead hands, be careful - the barrel will be very hot. - JSOP, 2013
I gotta fix the wife's all-in-one when I get home today...keeps crashing due to a problem with the wireless adapter failing on wake from standby...nice blue screen with a sad face...kinda reminds me of the old mac sad face that I used to see so much of. (OS 7.5.x)
I *highly* doubt that EseDiskFlushConsistency brought the system down... all this function does is flush database modifications to disk.
If you are interested in finding out what brought the system down then download WinDbg and open the minidump. If you setup the symbols... you will get the exact exception and entire callstack... Bugcheck 0x9F is a DRIVER_POWER_STATE_FAILURE meaning that one of the device drivers installed on your laptop improperly handled a power state.
Instructions for debugging a device driver power management error is here:
You will find exactly which driver caused the bug check. Always remember that Microsoft Windows allows third-party vendors to write device drivers. Don't be surprised if this is a third-party device driver.
Btw, once you learn how to use WinDbg you will probably not ask many questions[^]... because it's faster to just fire up WinDbg and get the answer.
4.2 Magnitude apparently, about 20km NNE from Swansea. A quick check on Google maps, and it was about 5 km from us.
The devastation is horrendous.
(The cat was spooked, and nothing even fell off a shelf.)
Send aid money for rebuilding now! Send it to me, and I'll coordinate it...
Still, explains the series of noises a few days ago: about 4am I was woken by a noise like a Parkinson's patient with a tea cup and saucer. Lasted maybe 30 seconds, then stopped. few minutes later, it's back. Could I find what it was? Nope. Now I know - probably a very small series of foreshocks.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
AntiTwitter: @DalekDave is now a follower!
Griff: Had a quake in Swansea.
You: Perhaps it was the one in Nantes 5 days ago.
Me: Swansea and Nantes are a long way away.
You: I am talking about the one Griff felt a few days ago.
Me: Was he in Nantes then?
You: What are you talking about.
In 2004, there has been an earthquake in Beaume-les-Dames (5.2 magnitude). I was home in Lyon and could feel it since my bookcase became suddenly shaky. Hence my question.
Now, I checked and indeed Swansea in quite far from Nantes. But on a geologic scale, not that far. I thought both these events, happening in a few days' window, could be somehow related.
