Additinal info:
I already got “same” BSOD in same module in Avast Free 18.3.2333.3860.316 in W10 1709 Fall Creators Update, so it was not caused by the newest w10 1803.

5

I forwarded it. Cheers

6

Still nothing about this BSOD.
Is there a solution ?
Where do I look for the status of my fileid 112XZ ?

7

As said, I forwarded it a couple of days ago (that’s all I/we can do).
Now it’s up to the devs to analyze your logs and come up with a fix…

Hi heikwith,
would you send us also the memory dump please ?

  1. Try to look for C:\Windows\memory.dmp or systems dumps can be stored in C:\Windows\Minidump directory.

  2. Zip the dump file and name it heikwith_aswstm.18.4.2338.sys_zip
  3. Upload the dump to avast ftp

It will help us with analysis !
Thank you

Strange that 2 guys are working on my problem:
I got an email from POLACH and this was my answer:
Hallo,
Sorry, I don’t have that memory.dmp anymore.
(If you like, I can resent you the AvastSupport folder created May 12 by the AvastSupportTool)
After May 12 the BSOD occured no more, so now everything with Avast works well.
Before May 12 it happened one or two times a week.

I am running now with 18.4.2338 (build 18.4.3895.325).
Not sure, but at May 12 I think Avast was still at build 18.4.3895.0.
I used avastsupport.exe v1.0.11.0 to create the AvastSupport folder.
Can that be the cause of the missing dump in your internal system ?
If yes, where can I download the latest one ?

Lets wait until this BSOD happens again.

Hallo.

I’m developer responsible for aswStm driver. I’m trying to find dump reported by you, but seems that something went wrong and then the file is not available through the internal system. Please, can you share the memory.dmp file directly to me through a google drive or other sharing platform?

Without the dump I’m not able to analyze where the problem is.

Thank you.

PS: Do you getting the crash on regular basis, or it occurred only once in the past and now everything works well ?
