[Dell G7 7588] *ERROR* Fault errors on pipe B: 0x00000080

[Alex Mantaut]

Hi,

Recently, I installed Ubuntu 18.04 on my Dell G7 7588. From day one, the system has random freezes/crashes (usually a few a day)

The way the crashes manifest is that 2 out of my 3 monitors go black and in some cases sound and inputs get stuck. In some rare cases, I can continue to operate on one of the screens.

I checked syslog and dmesg, and usually I don't see any messages at the time of the crash, except this one time that input did not freeze and I could run a dmesg. In that case I got this message:

Feb 13 15:34:51 morningstar kernel: [ 1593.615704] [drm:gen8_de_irq_handler [i915]] *ERROR* Fault errors on pipe B: 0x00000080
Feb 13 15:34:51 morningstar kernel: [ 1593.615999] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun

Additionally, this message appears on dmesg fairly often:
...
Feb 13 15:21:17 morningstar kernel: [ 780.324457] CPU6: Package temperature above threshold, cpu clock throttled (total events = 109)
Feb 13 15:21:17 morningstar kernel: [ 780.324457] CPU0: Package temperature above threshold, cpu clock throttled (total events = 109)
...

I tried to solve this issue on my own for a while now, without success, here are some of the things I tried:

- Updated BIOS to latest version
- Installed nvidia 415 graphic drivers
- Tested using xwayland
- Tried 4.15.0-45-48, 4.19.16 and 4.19.20 kernels (this last one generates problems with the graphic drivers, and does not solve the problem either.
- Tried modifying power management profile on the BIOS.
- Added splash acpi_rev_override=1 to /etc/default/grub as found here: https://www.reddit.com/r/Dell/comments/63cavx/fixed_nvidia_1050_freezing_in_ubuntu_linux/
- Ran dell diagnostic tools (no errors there)

So far none of this things solved the issue. These error messages are the only noticeable things I could find to debug...

Can someone help me find a fix or workaround the issue? I've been spending multiple days trying to solve this and I am not making any real progress

Please let me know if you need me to submit more information to find the cause of the issue

Those error messages are from the kernel so reassigning there.

However they may also be unrelated to the main problem you encounter so please also follow these instructions:

I am not sure how to decipher this but it seems like to be a hardware error. Please ask for Dell's support.
