Hello everyone,
I'm having some trouble with display output using meta-intel, if I boot
a core-image-sato image
and switch to a TTY, the screen goes black for a few seconds approx.
every 10 seconds.
I'm using the Thud release with linux-intel kernel v4.14.68.
This errormessage pops up in dmesg the first time this occurs:
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO
underrun
I've tried:
- Debian 9, with kernel 4.14.68 built from source => no problem.
- Without meta-intel => no problem.
- With meta-intel and linux-intel_4.19.bb from git => no problem.
- i915.modeset=0 => No flashing, but the resolution is much lower now.
- Sumo => same problem.
- These kernel parameters didn't help:
i915.enable_fbc=0 or 1
i915.enable_psr=0 or 1
acpi_osi="Linux"
Using acpi=off seems to work, but the system seems to hang on shutdown now.
Does anyone have an idea what could cause this?
Hardware: Fujitsu D3544-S3 with:
CPU: Intel Pentium Silver J5005
IGP: Intel UHD 605
