(see more with "efibootmgr) With grub-mkconfig -o /boot/grub/grub.cfg you configure grub - residing IN / boot/grub = THIS is the second part of grub !!

That is wrong. The mountpoint for the ESP should be NOW /efi (therefore you see in our AMD64 handbook a "mkdir /efi"). /boot is the standard directory for the kernel ... and it is NOW an ordinary directory of the root directory (so yes, the content of it resides in the root partition). Dont mount anything to /boot. Yes, a "make install" (or genkernel) installs the kernel into /boot. If /etc/fstab should be: /dev/nvme0n1p1 /efi vfat noauto,noatime 1 2 (IF this is your ESP) After mounting this ESP to /efi (and no mount on /boot + kernel IN boot) you should run: grub-install --target=x86_64-efi --efi-directory=/efi AND a grub-mkconfig ! (so this routine will find your kernel in /boot and add it to the grub's config file; Yes your grub will be also in /boot/grub.

I dont think you have a hardware problem because with 6.41 you have no problems. For me the following questions would arise: a) How did you install the kernel 6.1.41 ? (genkernel; dist-kernel; manual approach) b) Did you make any kernel configuration changes in your 6.1.41 ? c) Do you use a bootmanager ? (which ?; grub, refind ?) d) How did you update to 6.1.53 ? (every step) To better understand your system, I would look at the output of "parted -l" (complete), "dmesg" (complete), "lspci -k" and "emerge --info" (after you have booted 6.1.41). To clarify all this here via the mailing list might be difficult; therefore I would suggest to create a thread in our Gentoo support forum: https://forums.gentoo.org/ (I am there also; but we have also a lot of great experts there) If you create a thread in our forum, then please use wgetpaste for big files: https://wiki.gentoo.org/wiki/Wgetpaste Greetings, Peter

Re: [gentoo-user] 6.1.53-gentoo-r1 kernel not booting
If your system is working with your old kernel I dont think it could be a hardware problem. If your kernel config is the same then I dont think it is a problem with the kernel. My questions would be: Which CPU do you use ? Have you emerged a new microcode for CPU ? Example: Intel has disabled avx in some CPUs via microcode update. Now some applications may throw an illegal instruction ... and your problem description look like that only some programs have a problem. You could test it by compiling your old kernel again ... you should have then the same problem with it (of course you backup your old kernel before). Regards, Peter

Re: [gentoo-user] How to disable the modules service?
Rainer, the handbook still recommends to build sound modules (and many many others) as module, because it is easier than doing a static configuration. Now, you can ask, why someone wants to build it static into the kernel. The answer is: Security ! Maybe you know this wiki article: https://wiki.gentoo.org/wiki/Signed_kernel_module_support This is a pre-condition for enabling LOCKDOWN in the kernel ... OR ... you have NO modules support (=monolithic kernel) ! So, you have the choice which way you want to go. I am using a monolithic kernel also. Dont try to enable lockdown in your kernel if you use unsigned modules. ;-) I wrote a big warning in my wiki article: https://wiki.gentoo.org/wiki/User:Pietinger/Tutorials/ Kernel_Hardening_with_KSPP Regards, Peter Am Sonntag, 23.

Re: [gentoo-user] Root can't write to files owned by others?
Rainer, using sudo does not makes you a root user. To become a root user you have to switch with "su -" (and login with root password). Sudo has its own configuration file. If you can do something with sudo on other systems means there is a different configuration for sudo. Check "man sudo" Cheers, Peter Am Mittwoch, 9.

For this problem we have some articles in our Gentoo Forum. Between 5.10.x and 5.15.x there was a change: You dont have a "Simple FB" in your old directory (when doing "make menuconfig"); instead there is a new entry which leads to this in your .config: CONFIG_SYSFB_SIMPLEFB=y (Searching for "SIMPLE" in your .config gives you only this one + "CONFIG_DRM_SIMPLEDRM=y". If you have the old entry also in your .config, then you have not done "make oldconfig"). The "new" simpleFB is here: Device Drivers ---> Graphics support ---> [*] Simple framebuffer driver The old one was here: Device Drivers ---> Graphics support ---> Frame buffer Devices ---> [*] Support for frame buffer devices ---> Kind Regards, --P
