dmesg output with kernel parameters drm.debug=0x1e log_buf_len=4M

got a new HP Envy notebook and see screen continous flashing after some
seconds. Happens sometimes after 2sec, sometimes after 30s. Annoying

found dmesg entry

underrun

System is opensuse tumbleweed

uname -rm
4.5.0-3-default x86_64

attached dmesg output with drm.debug=0x1e

looks similar to Bug #94605
