Hi all

let me resurrect this thread. I am now working on this computer regular, lockdown has lessened here in Italy and I hope all you Devuaners are in good help.

Unfortunately stability did not improve much

We know it is a kernel problem since I can boot 4.9.0-11 boots fine (typing right now) while 4.9.0-12 crashes very soon (sometimes you can get to X and it freezes right thereafter) but most often it freezes directly at boot.

It is a hard freeze.


My CPU is:

model name    : Intel(R) Core(TM)2 CPU         T7200  @ 2.00GHz

I just tried adding "contrib" to my repositories and I see intel microcode is available, I hope it helps.

Do you know how this "update" works? will it be applied also when running older kernels?


I do not see it applied in dmesg when running 4.9.0-11

grep "microcode updated early to"


returns nothing.


Also I wonder if when running 4.9.0-12 it is applied early enough and if it would help at all.


I tried running 4.9.0-12  in recovery mode and I see the crash of the kernel.

(I did attach a screenshot, but it cannot fit inside the 40K of this mailing list, so I am removing it)
