Bug ID: 92079 Summary: Crash during load on wine d3dadapter during Heroes of the Storm loading Product: Mesa Version: 11.0 Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: patricknicolas@laposte.net QA Contact: dri-devel@lists.freedesktop.org

Since mesa 11, most of the times game loading crashes, either with a freeze or a blizzard error window. I use a Sandy Bridge IGP and a Radeon HD 7970 with DRI_PRIME, using dri3 and wine with d3dadapter (so it uses mesa d3d state tracker).

Sometimes, an error is printed in kernel messages: [ 7481.648047] radeon 0000:01:00.0: GPU fault detected: 146 0x0feb6014 [ 7481.648051] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x0000EEFF [ 7481.648052] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0B060014

I have bisected and the issue seems to come from

commit 719f124620d3c9b4d6ce14db3dbfc7af05626e5b Author: Axel Davy axel.davy@ens.fr Date: Sun Aug 9 19:06:01 2015 +0200

st/nine: Catch setting the same shader

This is quite rare that an app does set again the same shaders, but it isn't an expensive check either.

How can I provide more debugging info so we can find the specific issue in the commit ?
