Thanks Mark, it looks like it is a duplicate of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1829620 The temporary solution seems to resolve the problem for now. I added dis_ucode_ldr parameter to grub, and the system booted normally 3 times in a row, although still it shows ACPI errors in logs. Will keep updated if something more happens. ** This bug has been marked a duplicate of bug 1829620 intel-microcode on ASUS makes kernel stuck during loading initramfs on bionic-updates, bionic-security -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829784 Title: acpi(probably) random hang on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1829784/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
