drm-tip dmesg with drm.debug=0x1e from Lenovo Miix 320-10ICR

Hello!

I find that inserted microSD somehow cause issues with starting graphical
session on Lenovo Miix 320-10ICR. Please look into attached log for more
details, check part with following error message:
[drm:intel_dp_aux_xfer [i915]] dp_aux_ch timeout status 0x71450064

It's visible that backlight is enabled, but gdm3 (with enabled / disabled
Wayland) doesn't render anything. Enabling / disabling Wayland and autologin
doesn't change anything.

drm-tip 2019-07-30 4040b4c4ab647422d82100c8b091d34b6a82f572 log with
drm.debug=0x1e log_buf_len=8M from boot with inserted microSD is attached. You
can look into log without inserted microSD in <a class="bz_bug_link 
          bz_status_NEW "
