When I reboot the machine via Windows, the machine reboots normally and SSD is detected. However, when I reboot the machine via Ubuntu, the machine will reboot but it won't detect my SSD. I have upgraded to the latest Ubuntu distro and have the latest kernels, etc... I have validated that my installation and boot partitions are correct. Other people who faced an issue similar to mine were using SSDs with NVME. However, my SSD is SATA based, not NVME so neither applying the fix I found about setting nvme latency nor upgrading distro have solved the problem. On Windows, I had initially the same problem but on Windows after selecting AHCI Standard SATA mode, the issue was solved. On Ubuntu, I'm already in AHCI mode but the problem persists. I did few times grub boot repair to validate if it was something messed up with my boot configurations but turned out that it's not. I'm able to use Ubuntu 21 at the moment. However, I'm unable to perform a reboot. Every time I have to shut down the machine and then manually push the laptop's button to launch it again because if I accidentally hit reboot via Ubuntu, the machine will not find SSD and on next boot, the BIOS falls back into Windows Boot Manager and I have to run grub boot repair all over again via live USB. I hope that you will find a solution for this problem soon. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu71 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: ghost 2072 F.... pulseaudio /dev/snd/controlC0: ghost 2072 F.... pulseaudio /dev/snd/controlC2: ghost 2072 F.... pulseaudio CasperMD5CheckResult: unknown CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 21.10 InstallationDate: Installed on 2021-10-27 (33 days ago) InstallationMedia: Ubuntu 20.04.3 LTS "Focal Fossa" - Release amd64 (20210819) MachineType: LENOVO 20354 Package: linux (not installed) ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.13.0-21-generic root=UUID=6dee2b9f-b6dc-456a-9ee6-29269acb89f0 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 5.13.0-21.21-generic 5.13.18 RelatedPackageVersions: linux-restricted-modules-5.13.0-21-generic N/A linux-backports-modules-5.13.0-21-generic N/A linux-firmware 1.201.1 Tags: wayland-session impish Uname: Linux 5.13.0-21-generic x86_64 UpgradeStatus: Upgraded to impish on 2021-10-28 (33 days ago) UserGroups: adm cdrom dip lpadmin lxd nordvpn plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 07/21/2015 dmi.bios.release: 0.91 dmi.bios.vendor: LENOVO dmi.bios.version: 9BCN91WW dmi.board.asset.tag: No Asset Tag dmi.board.name: Lancer 5A5 dmi.board.vendor: LENOVO dmi.board.version: 31900059STD dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Lenovo Z50-70 dmi.ec.firmware.release: 0.91 dmi.modalias: dmi:bvnLENOVO:bvr9BCN91WW:bd07/21/2015:br0.91:efr0.91:svnLENOVO:pn20354:pvrLenovoZ50-70:rvnLENOVO:rnLancer5A5:rvr31900059STD:cvnLENOVO:ct10:cvrLenovoZ50-70:skuLENOVO_MT_20354_BU_idea_FM_LenovoZ50-70: dmi.product.family: IDEAPAD dmi.product.name: 20354 dmi.product.sku: LENOVO_MT_20354_BU_idea_FM_Lenovo Z50-70 dmi.product.version: Lenovo Z50-70 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1949029/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
