Some sample designs affected by the failure are Thinkpad X13, Z13, Z16. This failure doesn't affect resume with AC power or designs without LPDDR memory. [Fix] Upgrade yellow carp DMCUB firmware binary. https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux- firmware.git/commit/?id=4458bb4185b6d6e1f5c586fcf4b8cf6f5d3c8e24 [Test] Verify suspend/resume works. Verify that externally plugged displays haven't regressed. [Where problems could occur] Firmware is only loaded to Rembrandt designs. Regressions would be tied to those platforms.
