Hello guys,

 

does anyone here has already configure funtoo on a intel processor serie i7 with haswell as microarchitecture?

If yes, could post here to me the dmesg and the .config of the kernel?

 

I'm having a lot of trouble to make this work. And I really don't know why, but I'm almost sure that I've a hardware problem and not a kernel configuration problem, but I want to be sure, and I think I can be a little more sure if I compare my kernel configuration with the configuration of someone that has this configuration working.

 

Thank you guys!

Happy new year to all !!!

Nothing work... after a 15 minutes of system up I get kernel panic.

I notice that there is two different kind of kernel panic... one is that very famous drm_kms_helper kernel panic...

The other one just dump a lot of hexadecimal code in the screen.

 

I know that it's not a lot of information... I'm going to try to get some more, very soon.

 

Thanks for the help!

One more thing... even with the system rescue cd I get kernel panic, so I thinking hardware problem. It's most likely, right?

Or there is an aspect to cpu/hw you're missing. Like efi?
Not sure. Not familiar with later intel's.

A quick google search for "haswell kernel panic" didn't give me anything conclusive.

I've an i7 "Haswell" 4771 and I use for all FLAGS (CFLAGS, CXXFLAGS, FFLAGS and FCFLAGS) : "-march=native -O2 -pipe"

To see the active flags i use this script:

echo 'int main(){return 0;}' > test.c && gcc -v -Q -march=native -O2 test.c -o test && rm test.c test 

In a terminal

Then in another terminal

echo 'int main(){return 0;}' > test.c && gcc -v -Q -march=core-avx2 -O2 test.c -o test && rm test.c test 

 

Then with kate or gedit I can see simply the differences.

 

Same discussion was also for -march=core2 and -march=native; using -march=native, 2 o 3 flags or more are activated.

Maybe I'm wrong, but I don't think we've hit seeing use flags yet.
upc0d3 gets a kernel panic with System Rescue CD.

Something is not good with the setup. Collectively we're missing something.

General Question...
If you have a ufei machine with secure boot enabled, what happens when you try to boot a live-cd OS?

A secure boot enabled UEFI machine will only recognize and boot a signed medium. If you want to boot on a non-signed medium you must disable the non-secure mode.

A bit of a side track discussion to OP. But I had to ask.
Not OP's problem.

for such cases, it's good to select "Alternative kernel" first in Sysrescue, if this doesn't help, change media to something else, like Ubuntu live cd or any alternative ones.

The first thing that i make with a new PC is the complete memtest !!!

because in the past I've had several times troubles with Ram modules.
I've an assembled PC .
Here in Italy many retailers offers computers with "basic" kingston memories for show  "low  with prices" .

 

Instead I say NO !!!!! I want the hardware is good and have medium/great quality .

For example using Boinc ( 8 CPU + 1 x nvidia gpu ) the coretemps came to exceed 100 ° C : -o

Then I've bought a water cooler.
Using the system so exasperated ( Boinc , more compilation + Movies with XBMC ) , I do not see even a lost frame .
And I compile libreoffice in RAM ( 16GiB ) using / dev / shm .
My videocard is a MSI nvidia GTX 660 and also under intensive use so far I have not seen temperatures superior to 75 ° C .
Globally, thanks to water cooling Corsair H80i, either the gpu and cores ( i7 haswell ) do not exceed 75 ° C with Heavy Hard Load.
I could put a fan ( also 2 ) as substitutes for the case to dissipate better the hot "air in the case".

 

And not only for ram, I test the quality using benchmarks cause if i don't have hardware stability,

it becomes difficult to understand whether hardware or software error .

Excuse my logorrhoea :)
