The actual resetting appears to be on line 711 with:
[    9.867926] [drm:intel_panel_actually_set_backlight], set backlight PWM = 0

after two tries to get the i2c dp_aux_ch status (707-710):

[    9.865314] [drm:intel_dp_aux_ch], dp_aux_ch timeout status 0x5143003f
[    9.865321] [drm:intel_dp_i2c_aux_ch], aux_ch failed -110
[    9.867860] [drm:intel_dp_aux_ch], dp_aux_ch timeout status 0x5143003f
[    9.867866] [drm:intel_dp_i2c_aux_ch], aux_ch failed -110

Is this sufficient to take a stab at the cause?
Cheers
Dan
