Turns out 1.12 is a fairly old build and the working version in Ubuntu was from in Disco, therefore about a year ago. => https://launchpad.net/ubuntu/+source/seabios/1.12.0-1/+build/16284605
Therefore I built it in Eoan and even Disco. As an overview: Disco: gcc 4:8.3.0-1ubuntu3 binutils 2.32-7ubuntu4 Eoan: gcc 4:9.2.1-3.1ubuntu1 binutils 2.33-2ubuntu1.2 Focal: gcc 4:9.2.1-3.1ubuntu1 binutils 2.34-4ubuntu1 I ended up with these binaries to test: ./git-built-in-eoan/rel-1.12/bios.bin Breaks ./git-built-in-eoan/rel-1.13/bios.bin Breaks ./git-built-in-disco/rel-1.13/bios.bin Works ./git-built-in-disco/rel-1.12/bios.bin Works ./git-built-in-focal/head/bios.bin Breaks ./git-built-in-focal/rel-1.12/bios.bin Breaks ./git-built-in-focal/rel-1.13/bios.bin Breaks ./packaging/disco-seabios_1.12.0-1/bios.bin Works ./packaging/focal-seabios_1.13.0-1/bios.bin Breaks To summarize: - qemu breaks on chips of the Penryn generation - it only breaks if the seabios bios is executed - does not really depend on seabios or qemu version - but it depends on seabios build environment -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1866870 Title: KVM Guest pauses after upgrade to Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1866870/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
