The reason for all of the fuss about Hijack here, is that the stock empeg kernel was produced back when hard drives were all much, MUCH smaller than the LBA28 limit of 128GB. So the stock empeg kernel predates large drives, and is unable to correctly deal with them. Whereas Hijack has been continuously maintained since its inception, and includes LBA48 (big disk) support.

I think maybe the v3alpha kernel also has LBA48 support, but possibly still buggy.
