Linux vs Meltdown: Ubuntu gets second update after first one fails to boot
Canonical, the company that makes Linux distro Ubuntu, has re-released its Meltdown update for Ubuntu 16.04 LTS Xenial users after the first attempt tripped up machines.
Canonical managed to get its fix for the Meltdown CPU bug out on Tuesday as scheduled, but was forced to issue a new release after discovering some 16.04 LTS Xenial users couldn’t boot their machines once the update was installed.
Several users reported the same problem after installing Ubuntu 16.04 LTS with the kernel image 4.4.0-108, with some reverting to the previous working kernel to resolve the issue.
“Just got the Meltdown update to kernel linux-image-4.4.0-108-generic but this doesn’t boot at all. It just hangs after grub,” wrote one user in a bug report.
On Wednesday, Canonical posted a new security notice confirming the problem as well as a second update with a new Linux kernel image, 4.4.0-109.
“USN-3522-1 fixed a vulnerability in the Linux kernel to address Meltdown (CVE-2017-5754). Unfortunately, that update introduced a regression where a few systems failed to boot successfully. This update fixes the problem. We apologize for the inconvenience,” Ubuntu said in the new notice USN-3522-3.
Several users on Ubuntu forums have since confirmed that the update with the 4.4.0-109 Linux kernel image resolves the freezing issue.
