When I upgraded Ubuntu 21.10 to 22.04, I got this error at boot. The laptop boot time changed from half a minute to 3 to 4 minutes. I want to know how to solve this problem, I am a new user of Ubuntu.

  • I didn't reinstall, I did the upgrade as prompted by the system. – yh l Jun 28 '22 at 01:47
  • I installed the Ubuntu system last summer, so it could be 20.04 or 21.04. – yh l Jun 28 '22 at 01:54
  • Thank you! I'll revise my question. – yh l Jun 28 '22 at 01:58
  • See if you can disable ACPI in your BIOS. That is failing on the LCD Brightness Control Module (BCM). You may have to try nomodeset for your grub to get past this. See: https://askubuntu.com/questions/38780/how-do-i-set-nomodeset-after-ive-already-installed-ubuntu – Terrance Jun 28 '22 at 04:03
  • I've set up nomodeset, but the Lenovo notebook bios doesn't offer the ability to disable ACPI. Is there any other way around it? – yh l Jun 28 '22 at 12:32
  • With the nomodeset you can try also adding acpi=off to the /etc/grub/default file as well. Make sure that you run sudo update-grub before rebooting the system. – Terrance Jun 28 '22 at 23:37
  • ACPI has not reported errors, but there are still these errors. Booting always goes black for two minutes.[0.505865] integrity: Problem 1oading X.509 certificate -65 dev/nvme1n1p2: clean, 1788842/61022208 flles , 34540926/244059136 blocks [2.908797] nvidla-gpu 0000:01:00.3: i2c t meout error e0000000 [2.9088291] ucsi_ccg 0-0008: i2c transfer failed - -110 [2.9089021] ucsi_ccg 0-0008: ucsi_ccg_init failed - -110 [ 3.509761]j genirq: Flags mismatch irg 0, 0000080 (snd_hda_intel:card0) vs. 00015a00 (timer) [3.5098031] snd_hda_intel 0000:01:00,1: unabie to grab IRQ 0, disabling device – yh l Jun 29 '22 at 05:57
  • I don't think disabling ACPI is a good idea because it causes me other problems. I can't view my battery and use my touchpad. – yh l Jun 29 '22 at 07:06
  • Do you have Secure Boot enabled or disabled in BIOS? It should be disabled. The acpi was only a suggestion because your boot does show ACPI Error, but you might have a corrupted install as well. One other way to tell is to boot to a Live CD/DVD/USB and see if it completes boot. – Terrance Jun 29 '22 at 13:26
