Hi!

I have a problem with a Skoda Bolero (Delphi) 1Z0 035 156 G (HW 015, SW 0029). If I try to enter into the tone menu (sound button, Treble-Mid-Bass submenu) the HU turns off:

I've enabled the developer menu, and activated the SD logging. A txt file called postmortem was recorded, this is the end of the content:

Code:
+ postmortem data:
- kernel system down
- thread name:      hmi thread
- thread id:         71 (0x47)
- type:                    -16
- ercd:                      9
- inf1:             0x0875003E
- inf2:             0x00000101
Has anybody seen this behavior before? If yes, what could be the solution?
