Hey Steve,
Any chance do you have a http reference config for the mx53, I have
one of the original mx53loco's that I can't seem to get the sata
portition of the config work correctly..

btw: making sure:
CONFIG_PL310_ERRATA_769419=y
was enabled in the kernel and setting:
vm.min_free_kbytes = 32768
in /etc/sysctl.conf
Has really helped out the stability of gcc-testsuite/sbuild panda farm..
(and of course scheduling a reboot as soon as a 'kevent 2' error occurred.. ;) )
