Use Ubuntu 26.04 Live USB stuck on spinning circle (Try Ubuntu) on Intel Alder Lake N iGPU, works on 24.04.3

I am experiencing a boot issue with Ubuntu 26.04 Live USB.

On the same hardware, Ubuntu 24.04.3 works normally and I can enter the "Try Ubuntu" desktop without any issues. However, Ubuntu 26.04 gets stuck at the spinning loading circle after selecting "Try Ubuntu" and never reaches the desktop.

Hardware:

CPU: Intel Alder Lake N (e.g. N97 / N305)
GPU: Integrated Intel iGPU (i915 driver)
Display: Tested with both HDMI and DP

Tested systems:

Ubuntu 24.04.3: Works normally
Ubuntu 26.04: Fails (stuck on loading spinner in Live session)

Observed behavior:

Spinning circle appears indefinitely
No desktop is reached

I also tried booting with "nomodeset", but the issue persists or only partially progresses.

This strongly suggests a regression in the graphics stack (kernel / i915 / mesa / GNOME shell) in Ubuntu 26.04 compared to 24.04.3 on Intel Alder Lake N hardware.

I would appreciate any guidance or workaround (kernel parameters or driver settings) to get Ubuntu 26.04 Live session working on this hardware.

Thank you.

Comment: You're not specific with ISOs, as 24.04.3 ISOs were available using the GA & HWE stacks (6.8 & 6.14 kernels) but both are older than the 7.0 kernel found on GA or HWE ISOs of 26.04. If it's hardware related (esp. graphics), the kernel can be an involved. The first thing I'd check though is did you verify ISO checksum before write to media; did you check the write of ISO to media was perfect (unchanged? or you modified it via options & your modifications may not suit your hardware, thus your write method is the problem). Did you switch to a text terminal and explore ? (esp. if desktop)
