[Bug 1851054] Re: suspend fails - previous kernel works
With kernel 5.3.0-40 for me the suspend problem is solved. Still I face a resume problem.

[Bug 1851054] Re: suspend fails - previous kernel works
I verified my guess through providing a kernel parameter at startup xhci-hcd.quirks=0x0002 where the bit set is along xhci.h: #define XHCI_SLOW_SUSPEND BIT_ULL(17) This quirk provide nearly the same as the patch mentioned in #5. With kernel 5.3.0-28 and this parameter set the machine suspended without complaining :-) Unfortunately it did not resume :-( With kernel 5.0.0-37 and this parameter set the machine suspended and resumed without complaining. Since I misused the kernel parameter this maybe a side effect. If not it is a previously covered bug. This will be a new game. Again: If there is a kernel available with the patch applied I'm willing to test the patch. -- 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

I think the bug is related to https://lkml.org/lkml/2019/11/4/13 since the CPU of my computer is a Raven Ridge model.

[Bug 1851054] Re: suspend fails - previous kernel works
Then I compared to the behavior with the kernel 5.0.0-29-generic #31~18.04.1-Ubuntu with the proper suspend behavior from a user's view. There the computer also shows the kernel oops with * RIP: 0010:irq_startup+0xe1/0xf0 but i ends with a proper suspend. I've attached the snippet of this suspend, too. ** Attachment added: "journalctl output snippet of kernel 5.0.0-29" https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1851054/+attachment/5324635/+files/suspend-5.0.0-29.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
[Bug 1851054] Re: suspend fails - previous kernel works
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 :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
[Bug 1851054] Re: suspend fails - previous kernel works
The bug propagates through all kernel updates up to 5.0.0-36. I still stuck with 5.0.0-29. Meanwhile and additionally I tried some BIOS updates from Lenovo without luck. The last BIOS update was o4dj* from 10.2019. -- 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
