Subject: [PATCH 1/6] Revert "ACPI: CPPC: Adjust debug messages in amd_set_max_freq_ratio() to warn"
Date: Sun, 26 Apr 2026 22:55:15 -0500 [thread overview]
Message-ID: <20260427035520.1427080-2-superm1@kernel.org> (raw)
In-Reply-To: <20260427035520.1427080-1-superm1@kernel.org>
Some older systems don't support CPPC in the firmware and this just makes
noise for them when booting. Drop back to debug.
This reverts commit 21fb59ab4b9767085f4fe1edbdbe3177fbb9ec97.
Cc: stable@vger.kernel.org
Fixes: 21fb59ab4b976 ("ACPI: CPPC: Adjust debug messages in amd_set_max_freq_ratio() to warn")
