Lumia 640XL on 15063.414 - lots of 0x14B BSODs

[Puppy2016]

Hi,

I have Lumia 640XL LTE Dual Sim, only on production builds. There are a lot of BSODs lately, I can see it in Field Medic uploaded list

All of them are Bug Check 0x14B: SOC_SUBSYSTEM_FAILURE. Is possible to get the detailed BSOD report file to analyze it by kd ? The BSOD data points to SOC_SUBSYSTEM_FAILURE_DETAILS that have SOC_SYBSYSTEM_TYPE enumeration which could narrow what device the error comes from.

Thanks.

I got it. It is possible by Field Medic advanced options, System logs and crash dumps (Default or Full) https://docs.microsoft.com/en-us/wi...-tracing/use-field-medic-to-generate-a-report

The source of all the BSODs is: Response.BucketId=0x14B_SOC_SUBSYS_AUDIO_DSP_SFR_Init_wdog_or_kernel_error_suspected_IMAGE_qcsubsys8626.sys

It means:
BugCheck: 0x14B - an unrecoverable error was encountered in a System on a Chip (SoC) subsystem
Subsystem type: Audio digital signal processor (DSP)
Reason: SFR Init: wdog or kernel error suspected
Suspected driver: qcsubsys8626.sys
