[SOLVED] Testing, [i915]] *ERROR* CPU pipe A FIFO underrun

#1 Post by floreado »

Hi,

I see the mentioned message at system booting.
I looked around a little bit and I see that's an old bug which occurs from time to time after kernel upgrade.
I saw this message on kernel 4.12, 4.13 and now on 4.14.
I haven't seen any fllickering, black screen or something like this by now, but may I will have problems.
I have Haswell graphics card and currently I'm running kernel 4.14.
I can install 4.11 but it's an EOL kernel.
Is this bug dangerous for hardware?
I can live with it like it is and wait for next linux image, some day they must correct it but I don't know
if this is harmful for my graphics card.
Someone faces this bug, too?

Cheers

Hey, is it this problem:

The same message is mentioned in that bug. I don't know about any damage to the graphics card, but you should avoid the kernel version that is making the problem for now.

Hi,

Thanks for info.
I've switched to 4.11 since it works ok but it does not receive security patches.
I will keep 4.11, nothing else I can do.
I see that this bug occurs on every kernel, the rest depends on a particular machine.
