For a few of quickly noticeable issues: - PM is not working: at91_pm_sram_init: sram pool unavailable! - Watchdog is not even probed - on -ek boards the wm8904 is not probed either. Disabling CONFIG_DELAY_DEVICE_PROBES fixes all issues. Tomeu, what should I provide to help find out what's happening ? Sylvain
