The latest incremental Chrome OS 91 update caused quite a few issues, with far too many reporting that their Chromebooks were locked due to extremely high CPU usage. Google had to download the update and cause more issues in the process, but it looks like now, it has finally fixed the underlying issues. The incremental update is rolling out again, and everyone is happy ̵
As Chrome Unboxed reports, Google is rolling out the step-by-step update to v91.0.4472.147 again. While the version number is still the same as the one for the problematic update, it seems that Google solved what caused the problems under the hood, as there are no longer reports of reduced Chromebooks using this Chrome OS release.
After downloading the problematic update to version 91.0.4472.147, Google pointed to v91.0.4472.114 as the latest stable release. However, it looked like the Linux installer never got the note about the pulled update, as reported by Chrome Unboxed. The Linux installer needs to check if you are using the latest version of the operating system before it runs, and since version x.114 was not officially the latest anymore at that time, users were asked to update their Chromebooks. Since version x.147 was no longer available, it was not possible – x.114 was the last release at that time. Therefore, you could not install Linux.
While this issue is mostly solved thanks to the re-release of version 91.0.4472.147, Chromebook Pixel users are left in the dust. The 2015 device was unlucky enough to reach EOL (end-of-life) just when the problematic update was rolled back, so it is stuck on version x.144 which continues to claim that users need to update the computer to install Linux, even if Pixel no longer receives updates. The situation already led to many complaints on Reddit, but fortunately a solution has also been offered in the social network. You have to go to chrome: // flag / # crostini-use-dlc, set the flag to Handicapped, and you should be able to install Linux as usual.
We still hope that Google will update the machine one last time, because it is honestly not an elegant state to be left in, and it is anything but user-friendly.
The original issue of version 91.0.4472.147 slowed down some Chromebooks immediately after installation, with some owners reporting that even power washing and disabling all extensions did not resolve the issues. When you check the built-in Diagnostics app, it became clear that some process is locking the CPU, resulting in unusually high processor usage, 100% for some. It does not provide much respite for other activities.
At least it seems that not all Chromebooks were affected by the problem. We’ve only seen reports from devices with grunt and Hatch boards, although not everyone involved shared enough details to attach it to these two boards – multiple devices could have the same problem.
On the bright side, Chrome OS version 91.0.4472.147 fixes a long-standing bug that prevented some users from copying and pasting files to Linux apps (via About Chromebooks). Now that the update is rolling out again, you will be able to take advantage of it.
