Re: [CentOS] Where can I find more information on the recent update to the 4.18.0-373 kernel
I'm not sure how much freedom you have with your setup, but you could always try to use the elrepo-ml or elrepo-lt kernels. The elrepo-ml kernel follows the published version pretty closely, so for example right now I'm running 5.17.3 on my el8 boxes. The newer kernels solve a lot of hardware issues.

[CentOS] Where can I find more information on the recent update to the 4.18.0-373 kernel
Hello folks -- Is there any write up for the most recent update to kernel 4.18.0-373 specifically with respect to sound setup or anything really? I had been using an "alpha" driver for my Intel sound that was appended to my boot line up until this latest. This not only did not work but caused continual hangs. Edited the 4.18.0-373 kernel line and things got somewhat better...butthis version is loading A LOT of modules and do I really need them, etc. I am going through a lot of grief with this recent upgrade. Thanks for any help... -- Kay ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Installing mdadm and C7 on new computer
On 4/18/22 1:27 PM, H wrote: I have a new computer with 2 x 2TB SSDs where I wanted to install C7 and use mdadm for RAID1 configuration and encrypting the /home partition. On the net I found https://tuxfixer.com/centos-7-installation-with-lvm-raid-1-mirroring/ which I adopted slightly with respect to partition sizes, using RAID1 for /boot and /root as well and added the /home partition with RAID1 and chose to have /home encrypted. It may be a good idea to also have / and swap encrypted, since user data can go there easily (logs, locatedb, swapped mem). I would do: - /boot as a separate RAID1 (md1=sda1+sdb1) - then another RAID1 (md2=sda2+sdb2) using all the remaining disk - luks on top of md2, giving you luks-x - LVM with a PV on luks-x - VG and LVs for swap, / and /home (do not assign all the available space now, especially if using xfs as filesystem) Not sure if you can do this setup through the installer, you have to try (in a VM maybe).
