Hello There I've compiled the kernel for my UEFI system using the instructions of the books (LFS and BLFS) and when it boots it displays some errors (I append a kernel log snippet). The system boots fine but these errors are annoying and inmho slow the system boot. How can I solve the issue? I attach a link to my kernel config. I don't know why I've not enabled DRM_PANIC and DRM_PANIC_SCREEN. Can this be the reasons? The config file can be found here: https://raw.githubusercontent.com/michele13/initramfs/refs/heads/main/prebuilts/bzImage.config --- BEGIN KERNEL LOG --- [ 7.486610] drm_dp_dpcd_probe+0x3e/0xf0 [ 7.487155] intel_dp_read_dprx_caps+0x7c/0x90 [ 7.487703] intel_dp_init_lttpr_and_dprx_caps+0xbd/0x3a0 [ 7.488253] intel_dp_get_dpcd+0x20/0x140 [ 7.488806] intel_dp_detect+0x21b/0x7d0 [ 7.489352] drm_helper_probe_detect+0x47/0xb0 [ 7.489907] drm_helper_probe_single_connector_modes+0x405/0x650 [ 7.490459] drm_client_modeset_probe+0x25a/0x1880 [ 7.491020] drm_fb_helper_hotplug_event+0xa7/0x100 [ 7.491571] intel_fbdev_client_hotplug+0x7f/0x100 [ 7.492133] drm_client_dev_hotplug+0x99/0xf0 [ 7.492688] i915_hpd_poll_init_work+0x1fc/0x260 [ 7.493247] process_one_work+0x160/0x390 [ 7.493801] worker_thread+0x2a0/0x3b0 [ 7.494357] ? __pfx_worker_thread+0x10/0x10 [ 7.494913] ? __pfx_worker_thread+0x10/0x10 [ 7.495464] kthread+0xc8/0xf0 [ 7.496020] ? __pfx_kthread+0x10/0x10 [ 7.496566] ret_from_fork+0x2c/0x50 [ 7.497120] ? __pfx_kthread+0x10/0x10 [ 7.497667] ret_from_fork_asm+0x1a/0x30 [ 7.498213] </TASK> [ 7.498756] ---[ end trace 0000000000000000 ]--- [ 7.527612] ------------[ cut here ]------------ [ 7.528217] i915 0000:00:02.0: [drm] drm_WARN_ON(tc->mode != TC_PORT_TBT_ALT && !tc_phy_is_owned(tc)) [ 7.528221] WARNING: CPU: 7 PID: 64 at drivers/gpu/drm/i915/display/intel_tc.c:1757 __intel_tc_port_lock+0x80/0x100 [ 7.529334] Modules linked in: [ 7.529894] CPU: 7 UID: 0 PID: 64 Comm: kworker/7:1 Tainted: G W 6.13.1 #1 [ 7.530464] Tainted: [W]=WARN [ 7.531040] Hardware name: HP HP 240 G8 Notebook PC/868C, BIOS F.10 09/18/2020 [ 7.531614] Workqueue: i915-unordered i915_hpd_poll_init_work [ 7.532189] RIP: 0010:__intel_tc_port_lock+0x80/0x100 [ 7.532768] Code: 5f 50 48 85 db 0f 84 91 00 00 00 e8 ba ca 0a 00 48 c7 c1 d0 81 39 b9 48 89 da 48 c7 c7 36 1f 41 b9 48 89 c6 e8 51 99 7a ff 90 <0f> 0b 90 90 5b 5d 41 5c c3 cc cc cc cc 48 89 df e8 9b f9 ff ff 89 [ 7.533369] RSP: 0000:ffffa6e8402fb8d0 EFLAGS: 00010282 [ 7.533990] RAX: 0000000000000000 RBX: ffff9bff414692c0 RCX: 00000000fffff071 [ 7.534595] RDX: 0000000000000000 RSI: ffffa6e8402fb778 RDI: 0000000000000001 [ 7.535198] RBP: 0000000000000001 R08: 0000000000005235 R09: 00000000fffff071 [ 7.535805] R10: 00000000fffff071 R11: ffffffffb9658b60 R12: ffff9bff410f4000 [ 7.536403] R13: ffff9bff425ac1e8 R14: ffffa6e8402fb9a0 R15: ffff9bff425ac000 [ 7.537008] FS: 0000000000000000(0000) GS:ffff9c02afbc0000(0000) knlGS:0000000000000000 [ 7.537605] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 7.538198] CR2: 0000000000000000 CR3: 00000002e782e001 CR4: 0000000000770ef0 [ 7.538804] PKRU: 55555554 [ 7.539378] Call Trace: [ 7.539948] <TASK> [ 7.540506] ? __warn+0x84/0x130 [ 7.541072] ? __intel_tc_port_lock+0x80/0x100 [ 7.541630] ? report_bug+0x164/0x190 [ 7.542184] ? prb_read_valid+0x16/0x20 [ 7.542744] ? handle_bug+0x54/0x90 [ 7.543294] ? exc_invalid_op+0x17/0x70 [ 7.543854] ? asm_exc_invalid_op+0x1a/0x20 [ 7.544398] ? __intel_tc_port_lock+0x80/0x100 [ 7.544948] intel_dp_aux_xfer+0xc2/0x7a0 [ 7.545493] intel_dp_aux_transfer+0x130/0x330 [ 7.546047] drm_dp_dpcd_access+0xb3/0x140 [ 7.546593] drm_dp_dpcd_probe+0x3e/0xf0 [ 7.547139] intel_dp_read_dprx_caps+0x7c/0x90 [ 7.547685] intel_dp_init_lttpr_and_dprx_caps+0xbd/0x3a0 [ 7.548237] intel_dp_get_dpcd+0x20/0x140 [ 7.548787] intel_dp_detect+0x21b/0x7d0 [ 7.549330] drm_helper_probe_detect+0x47/0xb0 [ 7.549885] drm_helper_probe_single_connector_modes+0x405/0x650 [ 7.550435] drm_client_modeset_probe+0x25a/0x1880 [ 7.550993] drm_fb_helper_hotplug_event+0xa7/0x100 [ 7.551544] intel_fbdev_client_hotplug+0x7f/0x100 [ 7.552106] drm_client_dev_hotplug+0x99/0xf0 [ 7.552657] i915_hpd_poll_init_work+0x1fc/0x260 [ 7.553209] process_one_work+0x160/0x390 [ 7.553763] worker_thread+0x2a0/0x3b0 [ 7.554316] ? __pfx_worker_thread+0x10/0x10 [ 7.554874] ? __pfx_worker_thread+0x10/0x10 [ 7.555427] kthread+0xc8/0xf0 [ 7.555982] ? __pfx_kthread+0x10/0x10 [ 7.556530] ret_from_fork+0x2c/0x50 [ 7.557082] ? __pfx_kthread+0x10/0x10 [ 7.557628] ret_from_fork_asm+0x1a/0x30 [ 7.558175] </TASK> [ 7.558717] ---[ end trace 0000000000000000 ]--- [ 7.587612] ------------[ cut here ]------------ -- http://lists.linuxfromscratch.org/sympa/info/lfs-support Unsubscribe: See the above information page
