As per the subject line the following combination causes a signal 11 crash on S7 devices with a Snapdragon chipset:
Spawning an blueprint that adds an Instanced static mesh with a material containing a fresnel node causing a hardcrash of the device
With the help of Chris Babcock I was able to find this problem and it broke a running game
Note: Snapdragon only is affected - Exynos S7 devices have no problems.
I’ve talked with Chris on this one and I’ve reported this with UE-31051. This is something that has been passed along to Samsung and Qualcomm to investigate for the moment.
Do you see a message like this one in LogCat?:
W/Adreno-GSL(32053): : ioctl fd 34 code 0xc040094a (IOCTL_KGSL_GPU_COMMAND) failed: errno 35 Resource deadlock would occur
I unfortunately do not have a snapdragon device. Chris from epic was able to reproduce it for me.
