F38, Intel Skylake, Xorg and kernel 6.4.9

Ask Fedora

my brother running a notebook (F38, Acer Aspire E5-574-525M) in USA (I remote admin him via anydesk from Europe) got trouble running kernels beginning with 6.4.9.

It seem (I haven’t seen it myself) the kernel boots correct, but when it comes to the graph. login the screen goes black and nothing anymore.

GPU is Intel i915 and runs Xorg (cause of anydesk)

We have tried without “quiet rhgb” and journal doesn’t show something what could cause it.

I have searched (not in deepth yet) the bugzilla’s, but I couldn’t find something.

Anyone have an idea how to debug this or an hint ?

P.S.
we will try wayland next time …

What GPUs are installed?
Please post the output of inxi -Fzxx

I currently have no access to the device.

only the Intel iGPU: Intel HD Graphic 520

Notebook is running with Fedora since years (since 12/2015)

what we have also done:

  • 6.5 rawhide kernel
  • several boot parameter
    • systemd.unit=multi-user.target (=> runlevel 3)
    • systemd.debug-shell=1

and ctrl+alt+backspace ( restart X)

nothing !
screen goes just before graph. login black and the box seems dead

for the record:

boot parameter for kernel 6.4.11

mitigations=off

fixed it.

and of course switches all hw-Bug-fixes off (I know ! )

maybe with the upcomming kernel 6.4.12 there will be some changes to leave the boot parameter away …

+++ Edit +++
it seems the box has still trouble …

+++ Edit update +++
kernel 6.4.12 seems to fix it (and boots without “mitigations=off” too)

knock wood
