Hi, I notice a regression report on Bugzilla [1]. Quoting from it: > I've observed a slow boot and shutdown/reboot problems that have been verified on the stock Arch 6.5.1, CachyOS 6.5.0-2 and a custom-compiled 6.5.1 Kernel. I originally had seen a RCU-related trace which I thought to be the cause for these problems as well and reported it in https://bugzilla.kernel.org/show_bug.cgi?id=217864. However that specific trace turned out to be caused by an old patch that I carried around with me since 2022. > > systemd-analyze with my custom compiled 6.5.1 shows a suspiciously long firmware time: > Startup finished in 2min 42.000s (firmware) + 4.201s (loader) + 6.895s (kernel) + 1.541s (userspace) = 2min 54.640s > graphical.target reached after 1.539s in userspace. > > For comparison, 6.4.14 starts in 16 seconds and doesn't even show a firmware section. > > System: > Host: klx99 Kernel: 6.5.1-3.1-cachyos-lto arch: x86_64 bits: 64 > Desktop: KDE Plasma v: 5.27.7 Distro: CachyOS > Machine: > Mobo: Lenovo model: X99-TF Gaming v: G368J V1.1, NALEX > serial: <superuser required> UEFI: American Megatrends v: CX99DE26 > date: 10/10/2020 > CPU: > Info: 18-core model: Intel Xeon E5-2696 v3 bits: 64 type: MT MCP cache: > L2: 4.5 MiB > Graphics: > Device-1: AMD Navi 21 [Radeon RX 6950 XT] driver: amdgpu v: kernel > Display: x11 server: X.Org v: 21.1.99 with: Xwayland v: 23.2.0 driver: X: > loaded: amdgpu unloaded: modesetting dri: radeonsi gpu: amdgpu > resolution: 2560x1440~165Hz > API: OpenGL v: 4.6 Mesa 23.3.0-devel (git-8a32614a18) renderer: AMD > Radeon RX 6950 XT (navi21 LLVM 16.0.6 DRM 3.54 6.5.1-3.1-cachyos-lto) See Bugzilla for the full thread. FYI, it seems like this regression is related to systemd boot loop reported earlier [2]. To Marcus: On Bugzilla, Artem had asked you to bisect. Do you have any conclusion on it? Anyway, I'm adding this regression to be tracked by regzbot: #regzbot introduced: v6.4..v6.5 https://bugzilla.kernel.org/show_bug.cgi?id=217874 #regzbot title: slow boot possibly due to firmware (TPM?) issues Thanks.
