Status in linux package in Ubuntu: Incomplete Status in linux-oem-5.6 package in Ubuntu: Invalid Status in linux source package in Focal: Invalid Status in linux-oem-5.6 source package in Focal: Fix Committed Status in linux source package in Groovy: Fix Committed Bug description: [Impact] The machine connect with the external monitor on dock(Thunderbolt), Then system would hang during the boot-up. [Fix] The atomic check hooks must look up the encoder to be used with a connector from the connector's atomic state, and not assume that it's the connector's current attached encoder. The latter one can change under the atomic check func, or can be unset yet as in the case of MST connectors. [test] With the patch, The machine connect with the external monitor on dock(Thunderbolt), Then system boot up successfully. [Regression Potential] Low.
