2016/17 MBP w/tb Kernel panic after palmrest replacement

[Rford]

This is from a repair shop client of mine. They did liquid damage repair and ended up replacing palmrest of a 2016/2017 15" MBP w/TB. It runs for a while, then crashes and says:
*** Panic Report ***
panic(cpu 0 caller 0xffffff7f90ccb1b5): "Failed to quiesce supporting devices\n"@/BuildRoot/Library/Caches/com.apple.xbs/Sources/AppleACPIPlatform/AppleACPIPlatform-298.220.3/AppleACPIPlatformPower.cpp:1994

Ideas? Everything looks ok on board.

Could be anything. Most likely is corrosion on the board somewhere. Second likely would be of course shitty Chinese topcase picked from the trash. Disconnect touchbar LCD and touch connectors to rule out at least the touch bar. Also board could have been damaged, knocked off component, damaged connector, etc.
