I'm trying to find a Dell Latitude Chromebook to buy as my previous experience with it was great. And it looked and felt good also.

Some identifying features of said Chromebook:

• It was pretty small, probably had an 11" to 12" screen at max.

• Square-ish body that felt rubber-y on some parts.

• Micro SD slot.

• USB-C charging.

• It was some 2 or 3-in-one if I'm remembering correctly.

• Made between 2020-2021 or prior.

• Most likely an Education version of the Dell Latitude's.

• It had an Intel Pentium CPU.

That's about as much as I can remember.

Edit: Remember some extra stuff.

I tried searching up an answer but every result never gives me an in-depth explanation on why either a WiFi or Bluetooth adapter can't use the other protocol despite being on the same frequencies. Is it maybe due to power output or a hardcoded reason in the hardware itself?

Specs and versions:

Kernel: 6.12.90+deb13.1-amd64

Mesa: 25.0.7-2

Distro: Debain 13/Trixie

CPU: i5-2400

GPU1: Dell R5 430 OEM (Main GPU)

GPU2: Dell R5 430 OEM

Graphics Driver: AMDGPU (23.0.0-1) ^(damn, that old)

Additional info: I'm using radeon.cik_support=0 amdgpu.cik_support=1 in grub to enable AMDGPU over Radeon. glxinfo states that the Radeon cards are a "Radeon R7 200 series" but have no idea on the significance of that.

Main issue:

Every time I go to https://sketchfab.com, firefox-esr consistently crashes, and the only possible problem I see is an ACO error and unsupported opcode with ..src/amd/compiler/aco_assembler:1269. I found that it can be temporarily resolved by running with an AMD_DEBUG=usellvm flag.

Can I fix this issue or do I have to disable the ACO feature with the AMD\_DEBUG=usellvm flag?

Edit: Reddit formatting problems.

ACO ERROR: In file ../src/amd/compiler/aco_compiler.cpp:1269 Unsupported opcode: v1: %28:v[10] = v_lshlrev_b16 8, %27:v[10] Redirecting call to abort() to mozalloc_abort

Every time I go to sketchfab.com, the browser crashes.

The crash report used to give me a GraphicsCriticalError |[0][GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt (t=278.647) but not anymore because I probably fixed it by changing a grub boot config that disabled and enabled Sea Island(cik.support) instead of Southern Island(si.support) for Radeon and AMDGPU drivers, respectfully.

I think I know what the problem is as running a AMD_DEBUG=usellvm firefox-esr instance didn't crash.

I'm asking for help in trying to fix this issue.

Edit: Reddit screwed up formatting.
