I just try debricking WDL with 3Tb hard drive. I connected to UART port on board and may use console.
I boot board by tftp/nfs using run net_nfs command.
I use stock kernel image from apnc-021009-124-20111113.deb
But this kernel by some reason not determine sector size of my hard drive.
This is part of my output where we see that disc recgnized as 2Tb device:

I restored partitions except /dev/sda4 and booted it from hard disk too but after boot i see in dmesg same error…
so it means there must be some more configurations done for 3Tb drive.
