@Bob No worries at all

Bob

At this point the goal is to figure out which file, if possible

Though perhaps you could do a repair install

bertieb

I couldn't see anything obvious either in windbg or in BlueScreenView

I'll pastebin each

Bob

Sometimes you need to dig into the error params

Though this stinks crc fail or similar

In which case it's not guaranteed that the filename is even retrievable

And would likely need a kernel dump at least

stinks of*

@DragonLord Well to be fair the gcc error does tell you exactly what's wrong, but in a manner less friendly to newer developers

bertieb

@Bob Doesn't sound great, but we'll see how we go

pastebin.com/D5qsiYnn (BlueScreenView)

Bob

11:04 PM

The clang error is arguably too noisy for more experienced devs

@bertieb I'll take a look when I get to a computer

bertieb

@Bob pastebin.com/tNss24mR (windbg)

@Bob Cheers :)

Briefly, stack text:
[...] nt!KeBugCheckEx
[...] nt!PopGracefulShutdown+0x2c9
[...] nt! ?? ::OKHAJAOM::`string'+0xe30

BugCheck C0000102, {ffffc00001003150, 0, 0, 0}

Probably caused by : ntkrnlmp.exe ( nt! ?? ::OKHAJAOM::`string'+e30 )

DragonLord

@Bob Would have to agree with that to an extent; pretty sure there's a way to suppress that

Bob

11:32 PM

@bertieb ooookay

You might get some more info with a kernel dump and !object with the first arg (ffffc00001003150 this time)

or you can try that on the minidump

bertieb

@Bob I'll fire up safe mode and switch the dump type

Bob

Oh, another thing you could try: selectively enable individual drivers until you find the breaking one :P

bertieb

1: kd> !object ffffc00001003150
GetUlongFromAddress: unable to read from fffff8013dfce010
Could not read ObjectType address

Bob

@bertieb also, try inspecting the memory at that address: msdn.microsoft.com/en-us/library/windows/hardware/…

I'm hoping it contains the filename

(there's not much documentation on the ntfs errors, unlike the normal bugcheck errors)

@bertieb could also try ds on that address

Q: Is there an ethical standard for using Google Analytics?

I'm setting Google Analytics for my website for software that I'm about to release. When signing up there were numerous options and all were labeled secure and does not share data but some of it was confusing. Is there a set of options that are best for privacy of the user but also helps me as a ...

<sigh>

bertieb

Reference to syngery (km)

@Bob At that address I mean

Bob

o.O

was that with ds?

try uninstalling synergy from safe mode :P

actually, don't

make a full backup first

bertieb

ds just shows a bunch of what I assume is unprintables

Bob

in case something else breaks

@bertieb then how'd you find it?

bertieb

I could disable synergy service from autostarting

Bob

11:38 PM

@bertieb won't disable the driver

bertieb

@Bob memory browser as you suggested

Bob

or maybe it will, who knows

Hmm, I guess

@bertieb ah

antecsignature.com

11:39 PM

ds expects a certain string format

Ramhound

I really wish that case wasn't $500 :-(

Bob

not null-terminated

@bertieb won't hurt to try disabling the service

bertieb

@Bob Just doing so, will reboot

Bob

fingers crossed!

bertieb

The reference might be to a file is the confusing thing

Bob

11:41 PM

@bertieb ?

bertieb

Memory location reads \apps\synergy

That's about it

odd

Oh hello

D:\apps\syngergy:

The file or directory is corrupted and unreadable

Miiight be the culprit

Bob

11:42 PM

ha, that would do it :P

noooowww... how to fix it? :P

bertieb

Good question

Bob

hm. could try deleting it and seeing what happens

you might get a missing file error, but not an ntfs error

bertieb

How is Windows/NTFS at handling the removal of corrupted directories?

Bob

backup first

bertieb

shrug it renames okay

So will give that a try and see what happens; can always rename it back

Bob

11:43 PM

@bertieb the name is part of the parent dir's metadata

the object the dir itself points to is broken

bertieb

@Bob Yeah, but anything that references it should get a os file not found when trying to do a read I'm hoping

As opposed to a OHGODSCORRUPTION error :P

Bob

that's a git commit tree :P

(from the git project itself)

@bertieb yea, hopefully

I suspect Windows will cope with a missing non-critical driver

but just suicides at the first sign of corruption during driver load

tereško

@Bob looks like preparing for a release

bertieb

If this is the problem, the more worrying question is how did it become corrupted in the first place?

tereško

(I am assuming those are pull requests merged)

bertieb

11:47 PM

Success! (provisionally)

Bob

@bertieb you really need to check out the HDD SMART data sometime

and run 5+ memtest passes overnight

bertieb

@Bob I owe you a postcard (as mentioned) / coffee / beer at the very least

I could swear windows monitors SMART these days

I'll pull it up under Linux otherwise

Bob

@bertieb don't think so, but there's quite a few tools to do it (e.g. crystaldiskinfo)

bertieb

I'm sure I've seen notification ballon SMART warnings before

An older mobo I have gives SMART error notifications (that you have to F1 to dismiss before booting) during POST

Bob

hm. maybe just on fail states?

a couple reallocations isn't necessarily a failure yet, but could be indicative of one soon

bertieb

11:50 PM

Will smartctl just now anyways

@Bob Ah, true that, good point

0 reallocated sectors

Doing a short self-test --> passed

Bob

odd :\

definitely make a backup if you can

bertieb

Could have been a very unluckily mis-timed write

Yeah

At this point, I'm very happy that it didn't need a nuking

Couldn't have done it without your help @Bob

Bob

@bertieb ah, just a couple of tips and a wild goose chase (bootloader) here and there :P

you did most of it yourself

bertieb

So pick your just reward from the ones mentioned before, or I can write this all up as a question, and you can get the rep for the answer

I did the goose chasing in fairness (came in asking about bcd etc), you had the crucial windbg info

Bob

@bertieb if you can make it suitably generic (about the ntfs corruption error, or that specific error code), then that could help - there was a severe lack of resources for that code :\

bertieb

11:59 PM

I should write the question up anyway

There's yeah

You beat me to that :P

Bob

though it might be better if you self-answer - you know the exact steps you took
