Is there a definitive guideline for STABLE Linux kernel versions on Debian ?
Consider the details of this system.
:: cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"
NAME="Debian GNU/Linux"
VERSION_ID="12"
VERSION="12 (bookworm)"
VERSION_CODENAME=bookworm
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"
:: uname -a
Linux vm 6.1.0-33-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.133-1 (2025-04-10)
x86_64 GNU/Linux
Yes there is a reason why bookworm (Debian 12) is set on kernel version 6.1.x
series.
Please read the Reddit disucssion:
https://www.reddit.com/r/debian/comments/191dc5y/should_i_use_kernel_61_or_65/
6.1.x series is the one with which Debian 12 has been tested and is considered
the stable version.
Whereas, it is not that you cannot upgrade to other kernel version, it is just
that it isn't recommended.
