Regular crashes, kernel panic with 24.04 on tachyon @0xBB600000

is this some known reserved area?

I've been testing the different versions of of ubuntu and have found 24.04 extremely "delicate" and really doesn't seem to run well on my board. Admittedly its beta.

20.04 seems much much better, but as im sure your aware, is missing the GPU acceleration stuff.

well it looks like it's hitting memory reserved under memory pressure, needs a device tree fix
