Kommunikation mit Mesa 7i92 sehr instabil, Woran kann es liegen?

LinuxCNC updates never change the kernel.

Do you think i should stay on 2.9.10 as i am now , to keep my system running?
Or how often does LinuxCNC change the Kernel during updates?
I'm not keen on holding my breath after every update if the communication is broken..
 

Do not upgrade the kernel.
Or backup working one. The deb files can vanish from repositories, you must have them locally for restore.
For test you have to run LinuxCNC for many hours, for example leave it for night. You not need do anything, simply let works.
You have to disable screensaver and screen power savings, but this is common for all hardware and configurations.

Hi FOrum!

i have a Foxconn A74 Mainboard with 4GB DDR3_Ram, AMD Athlon X2 250 3Ghz.
I tried to upgrade to a graphicscard, i bought an Asus Radeon R7 240 with 2GB of DDR3 Vram.

Now my problems.. The latency overall is the same as with the onboardgraphics, bit i have massive spikes, up to 600000..

I tried: 

1.  Grub "radeon.dpm=0"
no luck, LinuxCNC greets me with a Readerror.

2. Grub "radeon.si_support=0 amdgpu.si_support=1 amdgpu.dpm=0"
no luck, LinuxCNC greets me with a Readerror. I checked which driver is used, it was amdgpu, but no luck.

As far as i can tell, the version without any kerneltweaks worked the best for me.

I have 1 Core isolated for LinuxCNC, nothing fancy in grub customized. 
Is there anything i can try to get the graphicscard to work properly?

Thank in advance, greets, TOm
