Hi, (not subscribed from this address, so please cc on any response) I came across a bit of an issue with the ARM uboot GRUB port today, which I believe will also affect the FreeBSD loader: http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=commit;h=fe1378a961e508b31b1f29a2bb08ba1dac063155 In short, the global data pointer has now moved from r8 to r9, and since no API bump was made as a result of this, software now needs to preserve both of these registers across calls into u-boot. If http://svnweb.freebsd.org/base/head/sys/boot/arm/uboot/start.S?view=markup is the correct version to inspect, the current loader is affected. Just a heads-up. / Leif
