[Ubuntu 18.04] USB Type-C test failed on GLK
Status in intel:
Status in linux package in Ubuntu:
Status in linux source package in Bionic:
USB Type-C ports would not be seen at ls /sys/class/typec/ some times, ie,
driver probe would fail. The fix just changes a timeout setting, allowing the
probe to succeed in those cases there is load on the system.
During boot, with the system at load, the probe would fail some times. With
the increased timeout for firmware responses, that doesn't happen after many
This would only impact systems that have this specific ACPI node. As the
probe runs on a work queue, this should not impact boot time.
