crash is supposed to handle compressed kernels just fine.
file /boot/vmlinuz-linux

i was chatting with someone on IRC #Kdump and supposedly arch kernel doesnt have debug symbols, so maybe it wont work this command or is it?
Thanks for the help ! at least i've been learning a lot of linux

Did you tell them about "crash: /boot/vmlinuz-linux: not a supported file format"?
This has nothing to do w/ debug symbols - what's the output of the file command?

yes i told them and they reply me that is likely vmlinuz-linux doesnt contain any debug symbols. and that i needed a kernel with debug symbols or these symbols are in a separate archive.
the output of file vmlinuz-linux is :

Linux kernel x86 boot executable bzImage, version 6.10.6-arch1-1 (linux@archlinux) #1 SMP PREEMPT_DYNAMIC Mon, 19 Aug 2024 17:02:39 +0000, RO-rootFS, swap_dev 0XC, Normal VGA

Hi all,

i am facing a similar problem.
My Hardware: HP ZBook 15 G6, Intel Core™ i7-9850H CPU, 32 GB RAM, 512 GB SSD
In the device there is a second GPU (Nvidia Quadro T2000 Mobile), but i don't have installed any Nvidia drivers so far. The display is provided by the Intel® UHD Graphics 630 adapter.

Problem is that the system shuts down intermittently while watching random videos on Youtube. It can happen twice a day, or the device is running for weeks without issues.
It also doesn't matter, which browser i am using. Tested on Chromium and Firefox.
I've tried native Arch and two different flavors (Manjaro, Endeavour) but the problem persists on all versions.

In case the system shuts down, i have to long press the power button, waiting until the Shift-Lock-Key is flashing. Then i can release the power button and switch the device on again.
Alternatively it works by removing the battery.

Any suggestions would be much appreciated. I've read in the HP support forum that this symptom can be seen by other users as well. But all they got as suggestion is to do a clean but and reinstall latest drivers. But these are solutions for Windows installations.

Thanks
Uwe

Problem is that the system shuts down intermittently while watching random videos on Youtube.

Unverpowered, overheated, bad CPU or RAM.
You don't have a ryzen CPU nor the haunted 13/14th gen intel CPU.

but i don't have installed any Nvidia drivers so far

If you're not using is, can you disable it in the BIOS/UEFI settings?

See whether you can avoid this by preventing the CPU from stepping down:
https://wiki.archlinux.org/title/Intel_ … Intel_CPUs

Or trigger it by stressing the CPU: https://wiki.archlinux.org/title/Stress_testing#stress

And unrelated to that check the RAM: https://wiki.archlinux.org/title/Stress … MemTest86+

And

twice a day, or the device is running for weeks without issues.

definitively keep and eye on the temperatures!

Also

watching random videos on Youtube … doesn't matter, which browser i am using. Tested on Chromium and Firefox.

Make sure you're not playing videos on the CPU.

Arch and two different flavors (Manjaro, Endeavour)

Manjaro and Endeavour are not "arch flavors" but different distributions.

Thank You for your reply.

i am pretty confident it's not underpowered or overheated.
The system runs fine even if i am converting 4K videos which is using all six CPU cores for hours. Never had a single drop there.

But while watching YT videos the fan doesn't even start and the CPU temperature is not significantly increased.
I can watch YT videos for hours but then selecting any other random video - the device goes off immediately once the video starts.

Your advice to disable it in BIOS is good, i will check it. I remember there is a switch at least for automatic selection of which GPU is used. Maybe i can turn this off.

What i forgot to mention:
I using KDE as my favorite desktop. And the system is not showing this behavior while using a RedHat based distribution (Alma, Rocky, Oracle), but it crashes too on Fedora, which is using a 6.x kernel while the others are still on a 5.x LTS kernel.
Could it be a Kernel topic too?

Thanks!

Spontanous cold reboots are a hardware/firmware issue, we're however looking for what triggers it and from your description it's more the CPU idling, so try to add "intel_idle.max_cstate=1 i915.enable_dc=0 ahci.mobile_lpm_policy=1" to the kernel parameters and see whether that stabilizes it (at the expense of more battery use)
If yes, you're essentially hoping to get away w/ something like "intel_idle.max_cstate=5" but it's not a good strategy to decrease powersaving slightly to ultimately figure that it doesn't help at all.
1. drastic measure for a stable baseline
2. enhance from there

MrSpock · 2024-10-27 19:49:15

Sounds like a good idea.

The ZBooks are not built for battery efficiency, these are mobile workstations which are pretty often used stationary.
I will give your suggestion a try and see how it impacts the battery life and if the crashes are going away.

Beside that the device doesn't really reboot. It simply stops working and goes in the "off" mode, pretty much the same if i would hit and hold the power off button. Wondering if CPU idling is capable to shut down the whole device. It's not even going into sleep mode, it is simply off.
Just realized that HP published a newer firmware for the device. I've installed it and will keep it running and monitoring for a couple of days before i am trying your config changes.

HP did not mention that a graphics problem is fixed, but you never know.....
