I've done some effort to get more information about the bug. 1. BIOS updates with the Lenovo tools are a bit confusing. I still stuck at the BIOS Version O3TKT46A from 07/21/2019. I've opened a support thread at https://forums.lenovo.com/t5/Lenovo-Desktop-Towers/V530-15ARR- Desktop-Tower-BIOS-update-confusion/td-p/4636769 .
2. I've recognized a difference in behavior since kernel 5.3.0-28-generic #30~18.04.1-Ubuntu: Wehn I put the computer into suspend it first does something like a kernel oops with * RIP: 0010:irq_startup+0xe1/0x100 and after that it shows a few lines later * PM: suspend_common(): xhci_pci_suspend+0x0/0xd0 returns -110 * PM: pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 returns -110 * PM: dpm_run_callback(): pci_pm_suspend+0x0/0x150 returns -110 * PM: Device 0000:04:00.4 failed to suspend async: error -110 * PM: Some devices failed to suspend, or early wake event detected then it follows endless repeating kernel oops with * RIP: 0010:dcn10_verify_allow_pstate_change_high+0x37/0x2d0 [amdgpu] I've attached the snippet of the journalctl output. ** Attachment added: "journalctl snippet with kernel 5.3.0-28" https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1851054/+attachment/5324634/+files/suspend-5.3.0-28.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1851054 Title: suspend fails - previous kernel works To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1851054/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
