2025-11-07: Validate GPU instability caused by VBIOS Following up on 2025_10_31-gpu_instability_verdict.md’s dependency change possibility, I’m checking if VBIOS was the root cause of the GPU instability. [!INFO] It’s not vbios Gathering GPU data To check VBIOS version that’s currently running: % nvidia-smi --query-gpu=gpu_name,vbios_version name, vbios_version NVIDIA GeForce RTX 5070, 98.05.28.00.BA Extracting out device info: device id: 2f04 vendor id: 10de % lspci -nnvvv -s 01:00.0 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GB205 [GeForce RTX 5070] [10de:2f04] (rev a1) (prog-if 00 [VGA controller]) Subsystem: PNY Device [196e:1439] Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 128 IOMMU group: 14 Region 0: Memory at d8000000 (32-bit, non-prefetchable) [size=64M] Region 1: Memory at f800000000 (64-bit, prefetchable) [size=16G] Region 3: Memory at fc12000000 (64-bit, prefetchable) [size=32M] Region 5: I/O ports at f000 [size=128] Expansion ROM at dc000000 [virtual] [disabled] [size=512K] Capabilities: <access denied> Kernel driver in use: nvidia Kernel modules: nouveau, nvidia_drm, nvidia Device was purchased on 2025-05-19 on amazon: https://www.amazon.com/dp/B0DYPGBX6J ...

2025-11-06: Issac Sim - Setup jupyter notebook with WebRTC Client While following Nvidia’s Issac Sim Tutorial 9: Pick and Place Example, I ran into an issue running the included python script examples for the Gipper Control Example. My setup consists of running Issac Sim in docker and interfacing via the IsaacSim WebRTC Streaming Client. The problem here is when following the Gipper Control Example and invoking python.sh, that does not latch on to the, already existing, running IsaacSim instance and instead runs an entirely new instance in the background (see IsaacSim: SimulationApp). ...

2025-10-31: GPU Instability Verdict After a long 2 days of investigation & fix attempts… it was bios. What happened? A couple days prior to flying to Michigan, I ssh-ed onto my PC and attempted a full system update, which updated packages from dec 2024 to oct 2025 o_O. Little did I know, it caused my PC to freeze. I think this was the beginning of the pain. The first day I got back to Michigan, I attempted to boot my PC but didn’t post due to VGA related issues. In order to fix it, I cleared the CMOS. ...
