Reboot sometimes hangs since 25.12.x (BPI-R4)

mar-co0711 · April 28, 2026, 9:15am

since OpenWrt 25.12.x sometimes my BPI-R4 Board hangs after reboot. But mostly there is no problem while booting.It seems there is a race condition problem caused through the Device Tree.I am using the SDCARD.IMG.GZ

Should be in the snapshots, if I read it correctly?

SNAPSHOT has the fix, yes. Personally I've added the patches to my 25.12-SNAPSHOT build and they seem to work fine there as well.
