The root cause is that the igc driver gets the error from NIC (provided by K2 dock) while performing NVM read IO. The driver lacks the mechanism to report the error and further runs the codes afterwards, which causes the unexpected 40~ sec. sleep and affected the Thunderbolt. [Fix] Cherry-pick the following patch from linux-next fixes the issue: bd2776e39c2a igc: return early when failing to read EECD register [Test Plan] 1. Install Ubuntu image and boot into the OS 2. Connect TBT monitor to SUT via K2 dock 3. Check if the monitor is working [Where problems could occur] May cause regression regarding some cases which were false positive beforehand.
