Flash in laptop with kernel 5.4

[Vctrsnts]

Hi,

I have a Lenovo Ideapad Y700 with GNU / Debian SID that has the following characteristics:

• - Linux 5.4.0-4-amd64 # 1 SMP Debian 5.4.19-1 (2020-02-13) x86_64 GNU / Linux
  - VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06) (prog-if 00 [VGA controller])
  • - In the BIOS I have selected that it works only with the internal graphics (that is with the Intel)
  - Intel (R) Core (TM) i7-6700HQ CPU @ 2.60GHz - Skylake

And the following packages that reference Xorg:

• - xserver-common
  - xserver-xorg
  - xserver-xorg-core
  - xserver-xorg-input-all
  - xserver-xorg-input-libinput
  - xserver-xorg-video-intel

And when the flash in file

Code: Select all

/var/log/syslog

I get the following error:

Code: Select all

kernel: [15990.152558] [drm: intel_cpu_fifo_underrun_irq_handler [i915]] * ERROR * CPU pipe A FIFO underrun

Instead, this before with kernel 5.3 did not happen to me.

I no longer know where to look and where to look, does anyone know where this problem may come from and how it can be solved?

Thanks a lot
