** Description changed: - From bug 2166531: + [ Impact ] - I have systems with AMD HWK CPUs, and I am encountering the same reboot issue after upgrading to 24.04 HWE kernel 7.0 + linux-firmware 0ubuntu3.1 - Without firmware update (0ubuntu2.27), reboot works fine. After upgrading firmware to 0ubuntu3.1, issue occurs. + AMD Hawk Point SoC systems fail to boot when running Ubuntu 24.04 with + HWE kernel 7.0 and linux-firmware 0ubuntu3.1. An accidental DMUB + firmware downgrade (0x08005300 → 0x08004800) causes the boot failure. + Users must force shutdown via power button. - Note: - - linux-firmware-amd-graphics is the latest 0ubuntu3.3 version. - - 6.17 oem kernel - DCN version in use is 3.1.4, display core version v3.2.340 - - 7.0 hwe kernel - DCN version in use is 3.1.4, display core version v3.2.369 - - When issue happens, only way to recover is to press power button to force shutdown + [ Test Plan ] - Do you know what might be the problem? + 1. Boot AMD HWK SoC system with linux-firmware 0ubuntu3.1 and HWE 7.0 kernel - observe boot failure + 2. Upgrade to fixed firmware package - system boots normally + 3. Verify DMUB version is 0x08005700 or later + + [ Where problems could occur ] + + Display firmware regressions could manifest as screen corruption, + initialization failures, or display pipeline hangs on AMD systems using + the affected DMUB component. Incompatibility between kernel driver + expectations and firmware interface could cause display subsystem + failures. + + [ Other Info ] + + Fix aligns Noble with Resolute branch firmware. Regression introduced + when linux-firmware 0ubuntu3.1 inadvertently included older DMUB binary + than predecessor 0ubuntu2.27.
