2021-09-16 New Kernel Releases

2021-09-16 – Kernel version 5.14.5-amd64-vanilla has been released.

This is a stable release As this is a vanilla kernel, change logs are available here: https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.14.5

Updates are available via the autoupdate app or using the server configuration tool.

2021-09-16 – Kernel version 5.10.66-amd64-vanilla has been released.

This is a longterm release As this is a vanilla kernel, change logs are available here: https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.10.66

This update is important. It specifically addresses a regression in posix-cpu-timers.c which would cause PHP applications, noticeably Nextcloud and WordPress, to display the following error:

PHP Fatal error:  Maximum execution time of 0 seconds exceeded

The temporary fix was to reboot into 5.14.3 or 5.10.64. The regression was present in 5.14.4 and 5.10.65. The permanent fix is to update to 5.14.5 or 5.10.66 and these are available as of 4:30 AM MST. Please run the autoupdate utility and reboot.

The kernels used in JCCHOME Linux are the standard plain kernels available from Kernel.org. There are no patches applied before being made available. While this may change in the future, performance and security optimizations have been applied faster this way.

We supply both LTS and Stable mainline kernels. We do not supply EOL mainline or testing kernels. For production we recommend the LTS kernel tree which is currently 5.10. When the next LTS kernel is available, the older 5.10 tree will still be maintained and so will still be made available.
