Interesting observation using Alpha 2 on an AC88U.
I don't recall seeing this Bad eraseblock message in older firmwares:

Does the new Broadcom SDK have a new NAND driver? Or, is my NAND having problems?
Hello, im also having same issue after flashing alpha2 on my new RT-AC88U, i still can send it back to vendor to get a new one unit... should i?
