Part Number: TDA4VM

Hi all,

It hard to reproduce. 

While we run the tidl a while  , sometimes  kernel panic happened!!!

Our kernel version is 5.10.120, j721s2(08.04.00)

Do you know what cause this problem??

The message as follow .

  • I checked the kernel panic info

    pvrsrvkm is gpu driver

    wave5 is staging media driver 

    Do you know what is the root cause of kernel panic?
