Notice of important AlmaLinux 9 update
by benny Vasquez 03 Dec '25

03 Dec '25

Hey friends! We released kernel-5.14.0-611.9.1.el9_7 a few days ago. We were alerted to an incompatibility with the kmod-nvidia-open-580.105.08-2.el9 module earlier today, making the NVIDIA module unavailable with the latest kernel after a reboot. This only impacted AlmaLinux 9 users. This has been repaired in kmod-nvidia-open-580.105.08-3.el9, which has been released. For more details see https://bugs.almalinux.org/view.php?id=590. If you have any questions, please do not hesitate to contact us: https://chat.almalinux.org Thanks! benny Vasquez Chair, Board of Directors @AlmaLinux OS Foundation *I am sending this message now because it suits me, but I don’t expect that you will read, respond to, or act on it outside of comfortable hours for your time zone.*
