Hi Petar, Thanks for the bisection, but it seems something is a bit off.
The only change between 5.4.0-26 and -28 is a patch for s390x, which is a different architecture, nothing to do with amd64, and no common files are changed. Could you please review the dis_ucode_ldr parameter is what you expected at these versions? If so, this might be due to a build-time difference or so. Thanks, Mauricio $ git log --oneline Ubuntu-5.4.0-26.30^..Ubuntu-5.4.0-28.32 e6579979377c (tag: Ubuntu-5.4.0-28.32) UBUNTU: Ubuntu-5.4.0-28.32 1b6b20ff872d UBUNTU: SAUCE: s390/mm: fix page table upgrade vs 2ndary address mode accesses b7c20a05a029 UBUNTU: Start new release 06b43e23d14f (tag: Ubuntu-5.4.0-26.30) UBUNTU: Ubuntu-5.4.0-26.30 $ git show --oneline --name-only 1b6b20ff872d6f4a5bd201f67ce36e21b62f2f55 1b6b20ff872d UBUNTU: SAUCE: s390/mm: fix page table upgrade vs 2ndary address mode accesses arch/s390/lib/uaccess.c arch/s390/mm/pgalloc.c -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1895458 Title: Computer freezes on kernel 5, works on kernel 4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1895458/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
