 Posted: Fri Sep 13, 2024 10:55 am Post subject: Troubles with Intel GPU on sys-kernel/gentoo-sources-6.10.* |
 |
|
I'm trying the sys-kernel/gentoo-sources-6.10 branch.
On headless machines, this seems to work fine.
On a Intel i7-11800H mini-PC desktop, the machine reboots violently from time to time (no panic message as far as I know) or slowly chokes and freezes. I am not 100% sure of the cause but I suspect the GPU, as this happened more often when I was running Steam games.
Did anybody have similar problems? What can I do to debug this issue?
cpuinfo & lspci :
model name : 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz
00:02.0 VGA compatible controller: Intel Corporation TigerLake-H GT1 [UHD Graphics] (rev 01) |

Sorry for the later answer. I'm now running 6.10.10 which seems more stable.
It includes fixes for AMD GPUs but not Intel AFAIK. Odd...

Because I had several other issues:
severe GUI slow down while running a game (Civ6 if that matters), odd dmesg messages (that I did not copied unfortunately) ...
emerge --info: https://bpa.st/AIODO
Why can't I upload the config files with wgetpaste?

Hmm ... you have a nice and fast system .... but your swap partition is REALLY too big ...

Try another service:
| Code: | $ wgetpaste -v --service 0x0 /usr/src/linux/.config
Your paste can be seen here: http://0x0.st/X3eU.txt |
(my old config for my i9)

Actually during some experiments I had to add swap.
I'm looking for a simple way to limit RAM usage for some processes by the way (I mean resident, not virtual memory). I could not do it with ulimit, I have to use cgroups

I see you have much experience with a kernel configuration, but I would change these:
| Code: | 1.
# CONFIG_X86_X2APIC is not set
2.
CONFIG_I2C_I801=m
3.
CONFIG_DRM_XE=m
4.
CONFIG_DRM_SIMPLEDRM=m
5.
CONFIG_FB=m
6.
CONFIG_FB_UVESA=m
CONFIG_FB_NVIDIA=m
CONFIG_FB_NVIDIA_I2C=y
CONFIG_FB_NVIDIA_BACKLIGHT=y
CONFIG_FB_RADEON=m
CONFIG_FB_RADEON_I2C=y
CONFIG_FB_RADEON_BACKLIGHT=y
7.
# CONFIG_INTEL_IOMMU_SCALABLE_MODE_DEFAULT_ON is not set |
1. Enable it you have an i7-11800
2. This is the only one you need (you can disable the others)
3. Disable it
4. Disable it
5. You must enable it statically to get EFI-FB. See: https://wiki.gentoo.org/wiki/User:Pietinger/Experimental/Manual_Configuring_Current_Kernel#Framebuffer_Device_and_Console
6. Disable them (after you have enabled VESA and EFI)
7. Enable it

Actually I should enable it on all my machines :-/
(at least 3 other where it is not enabled for whatever stupid reason) |

More stable but not entirely stable. The machine rebooted during the night.

(maybe clear your crontab?)

Or there is an error but it is not saved on the file system.
| Quote: | | (maybe clear your crontab?) |
I suspected that it could be triggered by some cron job, but they all look innocuous.
I had problems with scrub a while ago, but this is not that, I tried a full scrub and it worked fine.

You said you think there is no kernel panic; are you sure ? Maybe it would make sense to go from 6 seconds to 0 (wait forever) to be sure ? ->
| Code: | | CONFIG_PANIC_TIMEOUT=6 |
(also make sure that there are no settings in sysctl.conf ... like a -1 which does immediately a reboot)

It could be that whatever triggers it happens at a very low level, have you checked if the firmware was updated when the kernel was updated?
Possibly a silly suggestion, but have you already verified that the machine is not simply overheating?

I don't use KDE
I had another crash 2 days ago. Just before 2 pm. I have a cron job that starts at *:59
It just copies ~/Dropbox to a NFS share though rsync but I don't believe in a coincidence here. The job runs every hour and there are aoften new files, so it is not just the copy that triggers it.
Could I have an issue with the soft or hard lockups detection, or with my watchdog?
I disabled the NMI watchdog, just in case. I'm not sure I need it. |

It froze again during the night. The X11 GUI was frozen, the machine did not answer to ping, I could only reboot it.
How can I preserve the last kernel messages after a crash?
One detail:
After some investigation, I discovered that the iTCO_wdt watchdog did not work on this mini PC. I have another machine in the same situation.
AFAIK, iTCO_wdt works on all my other (old) machines.
If I understand correctly, iTCO_wdt is provided by the chipset and the motherboard manufacturer has to wire it correctly |

I am pretty sure now that it only freezes when I am playing Civ6 through Steam. Maybe this is related to Proton (Steam version of Wine) and not the Intel GPU driver.
I could not make any progress to debug this  |

if the cause is the GPU driver, it must be some rarely used 3D function. I would be surprised if it were only used by Proton. |
