"Firmware communication error" Kernel Panic on MacBook Air 2020

Hello,

I recently bought MacBook Air 2020 Core i5 model but often get the following "Firmware communication error" Kernel Panic during restart.

panic(cpu 0 caller 0xffffff7f86b93b81): "[IGPU] sendHostToGucMessage: Firmware communication error: no action response!\n"@icl/sched3/IGGuC.cpp:3599

Has anyone experienced the same error?

This happens almost always after high CPU load of Finder.

I clean installed macOS 10.15.4 using recovery option.

Thanks,

tyskey

Uninstall Parallels following their instructions or uninstaller, then see if the panics stop.

Hello,

Thank you for your reply.

I will try and also ask on the Parallels’ forum about this problem.
