It's a completely dirty hack and would not fix the issue completely. The EC= MT mutex is not only used by ideapad-laptop and ucsi_acpi, but also heavily us= ed elsewhere. If you really care about that, you can simply blacklist usci_acp= i as it also returns garbage due to the FW bug, see https://bugzilla.kernel.org/show_bug.cgi?id=3D221065#c34 --=20 You may reply to this email to add a comment.
