1274882 - Crash in nvwgf2umx.dll@0x7bdb85

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect, P3)

Description

[Nicholas Nethercote [inactive]]

This bug was filed from the Socorro interface and is 
report bp-de4cb38c-bc8a-44b8-8abf-84e6e2160521.
=============================================================

We've had 24 crashes with this exact signature in the past 7 days, in versions ranging from 45 to 49. But if you remove the crash address and just look for crashes in this DLL there are 424 in the past 7 days:

https://crash-stats.mozilla.com/search/?signature=~nvwgf2umx.dll&_facets=signature&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform#facet-signature

I looked at a few, some of them are bad reads, some are illegal instructions.

AFAICT this is an NVIDIA gfx driver. I see a range of adapters.

Milan, any thoughts?

The trick is to find crashes that have nvwgf2umx DLL, ignore the address, but look for CLayeredObjectRoot call in the stack, or even better, mozilla::layers::ImageHost::Unlock().

All the Nvidia driver crashes are going to have the same (close enough) DLL, so that doesn't help us much.  This is why we need bug 1274345 implemented.

It might be worth noting, there are three distinct Nightly users reporting this crash:

bp-0efa36a5-fbee-4bcf-bf42-467552160521
bp-fa96b289-cee6-43bb-b719-eb40f2160523
bp-d0ff7819-d0bc-4d85-ba00-050902160525

All three have dual GPUs with Intel 0x0116 on driver 9.17.10.4229 and an NVidia GeForce GT 500 series GPU on driver 10.18.13.5362.

We don't have a large sample size so take this with a grain of salt.

Closing because no crashes reported for 12 weeks.
