Good advice

Debian keeps the last installed kernel anyway and maintains symlinks to the root directory as /vmlinuz.old & /initrd.img.old and these can be booted from in an emergency, I think the auto-generated GRUB menu even has entries for them.

Yup, it does indeed.
I have the the installer image and Partedmagic in /boot/images as well, since I so thoroughly dislike unbootable systems. Never actually had a bad kernel from the Debian repos mind, force of habit from less reliable distros.

That's for sure, no matter witch kernel you use, it should be a rule. I think more than two of the same is exaggerated, to clarify that you can have more than one kernel installed with no major problem other than more update time.

and 4.9.0-4-amd64 for the backup.
I'm looking forward to 4.14 as it is LTS with support for six years.

It looks like kernels will soon create a 5%-30% slowdown in many processors due to working around a design flaw in Intel processors.

I'm happy now - Just installed Debian Sid/Butch AND succeded with installing the current nVidia driver without a glitch. Now I really love my Debian install.

Forgot to tell that I'm running kernel 4.15.0.1 on my system - Boy is that kernel fast.

And check the Meltdown/Spectre vulnerabilities in this kernel.

Backported the upstream Sid kernel for the MX 17 test repo on a vanilla Stretch pbuilder, except that I bumped the context switch frequency from 250 to 1000Hz, and of course changed it to be compatible with gcc-6 instead of gcc-7:

Finally i was able to upgrade kernel without losing performance..
I moved form 4.4.39 to 4.4.126 without losing performance..Testing it for four days, i feel a good performance.

I guess Meltdown is included by now.

Still using the highest available LTS kernels in both distros...

Same Devuan install since the first beta...

I keep PCLOS around (on a separate SSD) for multimedia and such...although, the last round of updates broke FF Multi Converter (won't even open and I'm too lazy to fix it

)...

Here's a little tip for you PCLOS users, new kernel install(s) may bork your sensors config, just run sensors-detect as root (assuming you have lm_sensors and hddtemp installed already), then re-config gKrellm or whatever your fave sensor app is.

Found a workaround for FF Multi Converter in PCLOS (it still wouldn't launch after the latest upgrade), I changed the Desktop launcher command to

Code: Select all

gksu ffmulticonverter

and run it as root, then change the files' permissions to users-read/write in Thunar as root. I have to down-covert TV shows to old .mpg(2), that's the only way my old/cheap DVD player's USB port will play them from a stick. Problem solved.

I guess Meltdown is included by now.

I went back to 4.4.39, I wont search for another kernel anymore. From that version on, my laptop come into cpu's obsolescence gap; my system (Extensa5230) works perfect with that version's kernel. Being In linux for several years and upon my own experience, I dont worry anymore about security threads, I'll priorize performance. I prefer to keep hold some apps and libraries in order to maximize performance and behavior if possible.
