I'm still using v4.20-rc7, and I wanted to try some more kernel parameters to narrow down the problem. Since the last kernel messages I got using earlyprintk (https://gist.githubusercontent.com/bmaupin/b743bb3325e100341c62ee62e713d8a4/raw/7372dddb5704d3f15ff429807355d5d3686165d2/boot7.png) were related to the Spectre mitigations, I removed noapic and replaced it with spec_store_bypass_disable=off and it booted. Oddly enough then I removed spec_store_bypass_disable=off altogether and it booted without any special parameters.
So I don't fully understand what happened, but it seems like my system boots fine now without any special parameters. I'll remove v4.20-rc next and see if it still boots with the kernels from Bionic. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808418 Title: Thinkpad T430u won't boot without noapic workaround To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1808418/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
