Loading initial ramdisk... you don't happen to see an "Out of memory" error when that happens, do you?

Testing with different Kernel versions shows that 5.18.19 works fine, without crashing on "Loading initial ramdisk...". This, unfortunately, won't create a single log file or crash dump, which makes error reporting hard, to say the least. System info: Laptop model: Lenovo ideapad 330S-15ARR CPU: AMD Ryzen 5 2500U with Radeon Vega Mobile Gfx x8 GPU: AMD Radeon Vega 8 Graphics RAM: 12GB - 2400MHz Description: Ubuntu Kinetic Kudu (development branch) Release: 22.10 Also, it is always necessary to add the "iommu=soft" command to the GRUB_CMDLINE_LINUX_DEFAULT line on /etc/default/grub, because no kernels will boot without it (this is an older issue). Even with this command, Kernel 5.19.X will always crash while loading the initial ramdisk. --- ProblemType: Bug ApportVersion: 2.23.0-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: matheus 1693 F.... wireplumber /dev/snd/controlC0: matheus 1693 F.... wireplumber /dev/snd/seq: matheus 1690 F.... pipewire CRDA: N/A CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 22.10 InstallationDate: Installed on 2022-09-18 (0 days ago) InstallationMedia: Ubuntu 22.10 "Kinetic Kudu" - Alpha amd64 (20220829) MachineType: LENOVO 81JQ Package: linux (not installed) ProcFB: 0 amdgpudrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.15.0-27-generic root=UUID=45a8c70a-d30e-4f97-ab4f-e761450b6302 ro quiet splash iommu=soft rcu_nocbs=0-7 processor.max_cstate=1 nopti pti=off amdgpu.gpu_recovery=1 ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2 clocksource=hpet amd_iommu=on amdgpu.dc=1 ProcVersionSignature: Ubuntu 5.15.0-27.28-generic 5.15.30 RelatedPackageVersions: linux-restricted-modules-5.15.0-27-generic N/A linux-backports-modules-5.15.0-27-generic N/A linux-firmware 20220819.git8413c63c-0ubuntu2 Tags: kinetic wayland-session Uname: Linux 5.15.0-27-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin lxd plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 11/04/2019 dmi.bios.release: 1.38 dmi.bios.vendor: LENOVO dmi.bios.version: 7WCN38WW dmi.board.asset.tag: No Asset Tag dmi.board.name: LNVNB161216 dmi.board.vendor: LENOVO dmi.board.version: SDK0J40679WIN dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Lenovo ideapad 330S-15ARR dmi.ec.firmware.release: 1.38 dmi.modalias: dmi:bvnLENOVO:bvr7WCN38WW:bd11/04/2019:br1.38:efr1.38:svnLENOVO:pn81JQ:pvrLenovoideapad330S-15ARR:rvnLENOVO:rnLNVNB161216:rvrSDK0J40679WIN:cvnLENOVO:ct10:cvrLenovoideapad330S-15ARR:skuLENOVO_MT_81JQ_BU_idea_FM_ideapad330S-15ARR: dmi.product.family: ideapad 330S-15ARR dmi.product.name: 81JQ dmi.product.sku: LENOVO_MT_81JQ_BU_idea_FM_ideapad 330S-15ARR dmi.product.version: Lenovo ideapad 330S-15ARR dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1990068/+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
