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... :mrgreen:
Code: Select all
Linux 4.9.0-0.bpo.6-amd64 #1 SMP Debian 4.9.82-1+deb9u3~bpo8+1 (2018-03-22) x86_64 GNU/Linux


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 :P )...
Code: Select all
Linux 4.14.32-pclos1 #1 SMP Sun Apr 1 01:46:38 CDT 2018 x86_64 x86_64 x86_64 GNU/Linux


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 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.

Code: Select all
uname -a
Linux debian 4.17.1 #1 SMP Fri Jun 15 13:24:38 CEST 2018 x86_64 GNU/Linux


I compiled the upstream kernel from source and installed firmware, including wl module from stretch-backports. Disabling debugging by using
Code: Select all
scripts/config --disable DEBUG_INFO
saved a lot of compile time, so it compiled in about 1h and 25 min.
I wanted to try out new power-saving feature.
My CPU is fluctuating between 0 and 55% for no apparent reason, and my hard drive is being active while doing nothing. As a result, battery is draining, fast. Surprisingly, Broadcom wi-fi card is working.
In short, try not to do this at home and stick to the Debian's kernel :D
I will try to remove intel-microcode, see if that helps.

Update: It seems to have been stable after installing stretch's microcode, not the one from backports. HDD activity is normal.
Update2: Removing microcode again, CPU seems to be at 100% sometimes when playing 720p+ videos on Youtube. This benchmarking is troublesome indeed.
And what-do-you-know, it worked.

You can also install ubuntu's kernel in 5 minits and avoid problems.., I would do so.. :twisted:, Im using ubuntu's kernel for tree year now Im too old to complicate my life.

By the way, Im now gonna install and test 4.17.1 now from ubuntu's ftp.

^Ok, report on how it goes on your end.
I compiled it because that's the best way to experience upstream stable kernel without extra patches from dowstream. Time spent on it didn't affect me since I wasn't doing anything special at the moment that required my laptop.

I removed intel-microcode, it works even better now than before. Plus I got rid of some non-free stuff, so there's that :)

Don't guess---install spectre-meltdown-checker to see for sure. Use the latest script from git to get the bad news about newer Spectre variants...not that there's any mitigation for those yet. :(

Thanks Steve,
I installed it... but I already went back to 4.4.39, I can live with Meltdown and company..they wont hurt me.

* Reduced performance impact of PTI: NO (PCID/INVPCID not supported, performance impact of PTI will be significant)
