Hi @kaihengfeng Yes, mitigations=off works on my ASUS pentium M (banias) machine with with ATI Mobility Radeon graphics, for all of 4.15.0-48, 4.15.0-50 and 4.15.0-51. At the moment, unable to check on the HP6710b laptop this bug was originally reported on, as I've loaned it to my brother.
Q: Were you suggesting mitigations=off as a solution (given the theoretical security vulnerabilities of spectre/meltdown), or just as a troubleshooting/diagnostic measure? I'm wondering if I would be better off sticking to 4.15.0-47 with mitigations on, or allowing other kernel patches with mitigations=off? Or 64bit linux may be the better solution, where possible/practicable. Thanks for suggesting the mitigations workaround!!! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1827884 Title: Boot problems after upgrade to kernel 4.15.0-48 (18.04.2LTS/i386) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1827884/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
