Created attachment 1767004 [details] Kernel messages 1. Please describe the problem: Booting Fedora 34 beta on a Lenovo Thinkpad T590 pauses for a while and then several complaints about soft lockups on CPUs appear. 2. What is the Version-Release number of the kernel: kernel-5.11.10-300.fc34.x86_64 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : It's occurred on the three Fedora 34 kernels I've used since upgrading to it: kernel-5.11.9-200.fc33.x86_64 kernel-5.11.9-300.fc34.x86_64 kernel-5.11.10-300.fc34.x86_64 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Happens on every boot. 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: (I will try this after submitting the bug report.) 6. Are you running any modules that not shipped with directly Fedora's kernel?: No 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag. Done. BTW there's also a tpm-related complaint in the dmesg. I believe that's a separate issue as it's been occurring since Fedora 33 without any noticeable impact. So that part is probably ok to ignore.
It seems to be fixed in the rawhide kernel (kernel-5.12.0-0.rc4.20210325gite138138003eb.177.fc35.x86_64) but back on F34 beta it reoccurs.
I updated my firmware today to LENOVO 20N4CTO1WW/20N4CTO1WW, BIOS N2IET94W (1.72 ) 02/18/2021 and it still happens: [ 2.659800] clocksource: tsc: mask: 0xffffffffffffffff max_cycles: 0x396d4bf570c, max_idle_ns: 881590425443 ns [ 28.277447] watchdog: BUG: soft lockup - CPU#0 stuck for 23s!

Created attachment 1782605 [details] softlockup trace from journalctl This has my kernel traces from my T590 as well, with the softlockup bug shown. Not sure why my kernel is listed as Tainted, as I'm not loading any modules.
Is this possibly the same issue in bug #1912167 ?
(In reply to John Apple II from comment #4) > Is this possibly the same issue in bug #1912167 ? I don't believe so. I've had tpm issues since before the soft lockups started and after updating to the 5.12 kernel the soft lockup has gone but the tpm complaints are still there.
Also have a Lenovo T590 and I encountered this exact issue even when running on Fedora 32; earlier this year I was affected after a dnf update and ended up reverting to kernel-5.10.13 which got me going again. It made the VMs I run on my system unusable because they would stop responding for minutes at a time in addition to the watchdog warnings at system start. I upgraded to fedora 33 yesterday and hit this again since the kernel was upgraded. Fortunately, I found kernel-5.10.13 in Koji built for f33 and downgrading to that once again fixed it. Locked it in with `dnf versionlock`. Not sure which kernel version this regressed in, but hopefully knowing that 5.10.13 was OK helps isolate.
5.12.5-300.fc34.x86_64 is now in updates-testing and it's working fine for me, no soft lockups nor tpm-related backtrace. If others still see problems with that kernel it would be best to file a new bug report as it'll be a different issue.
Upgraded to the latest packages with 5.12.5-300.fc34.x86_64 and most system services fail to start. I'm booting from the older kernel for now, but on my T590 networking won't start with the last update to 5.12.5-300 from about an hour ago.
