Hi, Sergey Could you please help to locate the line of code that causes oops, as below? 1. Compile the kernel with debug info Kernel menuconfig -> Kernel hacking -> Compile the kernel with debug info 2. Retest until it oops, here you get the address of code that causes oops. addr2line -e vmlinux Thanks, Lin Ming > > Sergey
