Hi all,
kernel 6.14.7 seems to have introduced a bug with AMD GPUs locking up constantly the whole system:

See issue [drm] ERROR dc_dmub_srv_log_diagnostic_data: DMCUB error on freedesktop git.
Reverting to 6.14.6 seems to mitigate the issue for now until 6.14.8 is available:
boot.kernelPackages = pkgs.linuxPackagesFor (pkgs.linux_6_14.override {
argsOverride = rec {
src = pkgs.fetchurl {
url = "mirror://kernel/linux/kernel/v6.x/linux-${version}.tar.xz";
sha256 = "sha256-IYF/GZjiIw+B9+T2Bfpv3LBA4U+ifZnCfdsWznSXl6k=";
};
version = "6.14.6";
modDirVersion = "6.14.6";
};
});
Anyone else with similar issues?
Please note that 6.14.7 was released to 24.11 and 25.05
