We found a issue ,after play music and reboot device
I2C bus is hanged because of sgtl5000
I see other people have encountered the same problem
Re: SGTL5000 hangs I2C bus after reset
But the patch of answer ,can't apply our kernel version
Please help to solve this issue

Hi charles
this link also mentions the same kernel patch for wandboard imx_3.10.17_1.0.0_ga
ASoC: sgtl5000: Fix the cache handling · wandboard-org/linux@55d6dfb · GitHub

you are using customized advantech linux, so it may be
recommended to apply to them for modifications.
Alternatively one can debug it using AN4553
Using Open Source Debugging Tools for Linux on i.MX Processors
