RC2 changes disk enumeration order

I’ve noticed an interesting change in the behavior of 11.4: it enumerates
the disk drives differently thna I’ve seen with other versions or
distributions. Specifically, the USB card reader (empty) is assigned sda-d
and the two SATA hard drives get sde and sdf assign. Not a real problem
except for a few scripts that survived from 11.3 and before which enumerate
the USB attached card reader after the two SATA drives but I’m curious: is
this a known change in the kernel or just some quirk of this system (Lenovo
J3000, AMD64 Athlon x2)?

Any way to force the two primary hard drives to be enumerated as sda and sdb
as before just for compatiblity?
