I suspect there's a defect in signed-ness handling somewhere, or simila= r =E2=80=94 however, it appears to be cosmetic and disappears when the OS= D replay completes. (I've likewise seen impossible values for other statistics being reported =E2=80=94 a while back I saw multiple EBs being reported as be= ing read/written during a resync between 4 disks, for example. I suspect this is another manifestation of a similar problem.)
