Fix the SuperMicro H8DME-2 early-boot 50 sec stall. Somewhere between r5491 and r5496, a change occured which added some 30-50 seconds to the boot time of a Supermicro H8DME-2. This rises by an additional 30-50 seconds if the boot sequence decides it needs to reset-restart.
The problem was traced to a printk which was enabled somewhere between those two svn revisions. Apparently this printk appears too early in the boot sequence to function correctly. This patch again comments out the printk, but this time around, adds an explanation, to encourage future maintainers to keep it commented out. Please apply.
