It has an attached usb3 disk which is ZFS and has the data. The guts of the OS is on the sdcard though. It's been working fine up till a week or so ago when I decided to=20 update FreeBSD. On reboot it failed to come back. It normally runs headless and keyboardless. I found that the machine would boot normally *only* if a screen was plugged into the HDMI port. If the screen was disconnected, console output revealed= =20 eventual drop to debugger a short while after: sdhci_bcm0-slot0: Controller timeout (In the output there is also "Root mount waiting for: CAM" but this is=20 deliberate and is there to allow usb3 to wake up before ZFS) The controller never times out if HDMI is attached. I thought at first it also needed a keyboard but that's not the case. boot failure:=20 https://cloud.zyxst.net/~john/FreeBSD/current/rpi4b/badboot.txt successful boot: https://cloud.zyxst.net/~john/FreeBSD/current/rpi4b/goodboot.txt thanks, =20 --=20 J. --e5hxcFVa8xaKV392 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE8n3tWhxW11Ccvv9/s8o7QhFzNAUFAmAA8gcACgkQs8o7QhFz NAV5sA/+KegMbIOmZz/99Xnyt43V4HGfdPi8TsXyNLKkSbmfPeW1CaYUxa04tiIi TXVYhNhis3p80xsZ7hH9bhSkyLAEr9bGALTkHJSoQH9fFQ3QKxxXr7mFkkjY2Yi3 qBz9TTpm656WNxg7ls7be/64G5OxiUv5Peqju0ErrPWPJgwMCiInjVIDGWHF2sVn RAPAxu/VMcOTMottrOkpO8i7hLslMExXY8OtnfMi6n1lPUy5AU5y59Iqh6xsLEoP 7wmmgRtu05GZ69YnWEPIkkcGibdtP1L6Bi0x+3tYneHSTGvoTRHieedL67CdKChd IfHZJKy80aNF+UAHGuEeQAUzKcQke+fjGgNDTImASc1URMXYi6XtMfsoz+S5UTnQ lb2gEpZTbK4zHGOK+8zvg0KYJL4bcbFr/v2Xr17HBHK+1pHmGREJ1+t/nSplAKpb BlrhGvw7YeJQzeWSlM96S0gj0pW+dpaa4UV+k+PqiYI4YddLR2BlSwwxbha4cySp /qPSA/KDgOgi3P/dSim0luoElf2cGbrIqObQkySftRT/Q+CREyo/MyDNmW7Wj61c eQqQBhqC86jTQxTz9t2pqp5FiaD85Htu1QhXpm/pPbCoGdjhW/by6PgAz8vGd+f+ RAk9CMeF0418oejoG14Jo1igMwJMVIgStheTkbSWx6M4VfNvInI= =vSEB -----END PGP SIGNATURE----- --e5hxcFVa8xaKV392--
