These symptoms all go away with PSR-SU disabled for this TCON, so disable it for now while DMUB traces [2] from the failure can be analyzed and the failure state properly root caused. (cherry picked from commit afb634a6823d8d9db23c5fb04f79c5549349628b) The Linux kernel CVE team has assigned CVE-2024-50108 to this issue. Affected and fixed versions =========================== Fixed in 6.1.115 with commit 5660bcc4dd53 Fixed in 6.6.59 with commit c79e0a18e4b3 Fixed in 6.11.6 with commit fc6afa07b5e2 Fixed in 6.12-rc5 with commit ba1959f71117 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2024-50108 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/amd/display/modules/power/power_helpers.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/5660bcc4dd533005248577d5042f1c48cce2b443 https://git.kernel.org/stable/c/c79e0a18e4b301401bb745702830be9041cfbf04 https://git.kernel.org/stable/c/fc6afa07b5e251148fb37600ee06e1a7007178c3 https://git.kernel.org/stable/c/ba1959f71117b27f3099ee789e0815360b4081dd
