[solved] Opening LibreOffice seems to stall/crash system

Hello there!
I have a problem about opening libreoffice, as it seems to stall/crash my whole system.
Most of the time on opening libreoffice, I get panics in the kernel log and several tasks begin to hang.
Sometimes opening libreoffice is successful, but on closing it, the upper behaviour occurs.

System is a Framework 13 Laptop with AMD Ryzen 7 7840U w/ Radeon  780M Graphics on BIOS 3.09, 64GB of RAM and 4TB of SN850X.
Arch is booted using UKI and Systemd with Secureboot (own keys) enabled.
cmdline despite neccesary stuff is:  lockdown=integrity lsm=landlock,lockdown,yama,integrity,apparmor,bpf rw quiet splash rtc_cmos.use_acpi_alarm=1
Kernel is 6.15.9-arch1-1
Using Gnome on Wayland

3 dmesg on opening libreoffice:

Any help debugging this is greatly appreciated!

EDIT: A BIOS Update seems to have resolved the issue. see last post

memory related, pointing towards amdgpu and amdxdna => Does https://wiki.archlinux.org/title/LibreO … or_crashes stabilize things?
Do you *only* have this w/ libreoffice or also other EGL/GPGPU clients?

Re: [solved] Opening LibreOffice seems to stall/crash system

Thank you!
STarting libreoffice with the env to disable OpenCL (SAL_DISABLE_OPENCL=1 and SAL_DISABLEGL=1) does not crash or stall the system.
I also seem to have forgotten to install opencl-mesa, but after installing it the symptoms are the same.

I am not aware of other EGL/GPGPU clients that have problems on my system, do you have any suggestions to test?

I also noticed some log entry in the kernel buffer upon running clinfo:
"amdgpu: Freeing queue vital buffer 0x7f42cf400000, queue evicted"
whereas the address changes with every occurrence/run of clinfo.

Output of clinfo:

Output of eglinfo:

Starting libreoffice with RUSTICL_ENABLE=radeonsi to use rusticl instead of AMD Accelerated Parallel Processing from mesa results in the same behavior.
dmesg of that try:
https://paste.systemli.org/?ef967eb81e2 … rExNQY42cG

also something of interest when using AMD APP:

[  198.973915] BUG: kernel NULL pointer dereference, address: 0000000000000010

Re: [solved] Opening LibreOffice seems to stall/crash system

Do you need to disable both features or do you get away w/ disabling only one? (So we know where to look specifically)

Do you get  the same errors when booting w/ "processor.max_cstate=1 iommu=soft", https://wiki.archlinux.org/title/Kernel_parameters ?

Hey,

bisected it further and only starting LibreOffice with SAL_DISABLE_OPENCL=1 keeps it from crashing.
Besides that, using the soft IOMMU but keeping the full range of cstates also resolves the issue, so that SAL_DISABLE_OPENCL=1 is not necessary anymore.

Guess theres a problem with the AMD HW IOMMU then?

Updated the BIOS from 3.9 to the recently released 3.16 and removed the "iommu=soft" from kernel cmdline to test if the issue had something to do with it.
The issue no longer occurs upon opening LibreOffice.
