Working on a Buildroot OS with kernel 6.18 + PREEMPT_RT on an Intel AX210 WiFi (iwlwifi QuZ firmware). With dynamic preempt everything works, but RT causes firmware init errors and the device disappears. Maybe bleeding-edge RT kernels aren’t always the best choice. Curious if others hit similar issues or found workarounds. Open to discussion.

Milestone unlocked 🚀
Built a custom Linux system with Buildroot + PREEMPT_RT on x86_64, fully functional and minimal, supported by a local AI assistant with RAG, trained on official docs: no hallucinations, only grounded answers.
Real-time Linux, reproducible builds, full control.
This one feels big.

Update after longer run (~10M cycles): max jitter reached 55 µs 👌🏻
Plugging in AC power caused a localized spike on a single RT thread (51 µs), while others stayed stable.
Classic ACPI / power-state event: bounded, localized, fully recoverable.
Determinism preserved under real hardware events 👊🏻

Built a custom RTOS with Buildroot + Linux 6.12 RT. Tested on an old Celeron dual‑core over SSH, Wi‑Fi on, and stress‑ng running.
Max jitter: 39 µs (!)
Same hardware, same kernel on Debian 13 RT in “clean lab” conditions… also 39 µs.
Real‑world vs lab, same result. Buildroot wins in determinism 🏆

Built a custom Buildroot distro for #Raspberry Pi 4 running:
Linux 6.12 PREEMPT_RT, Wi‑Fi, #NordVPN, #Tor + #Proxychains, #macchanger, #nftables, #nmap, #netcat, #watchdog.
A real‑time, stealth, weapon‑grade network appliance.
Minimal. Fast. Untraceable. Mine 👊🏻

🚀 BashCoreZ is out now at https://bashcore.org 🤟🏻
The purest BashCore ever, based on Debian 13 “Trixie” and Linux 6.12.
Zero bloat, zero persistence, zero extras 😎
🔥 New: choose at boot between the dynamic or PREEMPT_RT Real-Time kernel directly from GRUB: perfect for audio, robotics, and time-critical tasks 👊🏻
I’ve had another crazy idea, and I’m already working on it 🤟🏻
I never thought I’d end up playing with the PREEMPT_RT kernel, but here we are.
Beyond its use in embedded systems, this opens the door to something new, something useful, and I honestly don’t think anything like it exists yet 😎

🚀 New BashCore Releases Are Live!
BashCoreT & BashCoreTX now available, built on Debian 13 "Trixie" stable with Linux Kernel 6.12 and PREEMPT_RT realtime support.
🧵 BashCoreT: CLI-only 👊
🖥️ BashCoreTX: XFCE desktop 😎
Download now on SourceForge:
https://sourceforge.net/projects/bashcore/files/releases/

Assigned 8 cores and 8GB RAM to BashCoreTX on my MSI Katana (i7 / 32GB).
TX runs like a razor, even inside VirtualBox.
Fast, clean, stable, silent.
XFCE + Kernel 6.12 + Debian 13: more than enough power, without waste.
