The original one was triggered by S3 and probe failed with the following error: *ERROR* LSPCON read(0x80, 0x41) failed The one in patchwork_2888 happens independent of S3 with the following error: [drm:drm_dp_dual_mode_detect] DP dual mode adaptor ID: 44 (err 0) [drm:lspcon_init [i915]] No LSPCON detected, found type 1 HDMI [drm:lspcon_init [i915]] *ERROR* Failed to probe lspcon In this latter case LSPCON recovers, and looks like the same issue we have with some type 1 dongles where the read offset during I2C-over-AUX transfers is ignored by the dongle.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
