Description of problem:
The XFS filesystem on a raw disk crashes after updating packages on the root filesystem which is on a different disk.

Version-Release number of selected component (if applicable):
drakxtools-backend 18.21-2.mga8

How reproducible:

Steps to Reproduce:
1. Create a XFS filesystem on /dev/sdX (not on a partition), mount it, write some files to it
2. update a bunch of packages on the system [my guess: install a new kernel]
3. wait a little while

I'm filing this bug on drakxtools-backend because I guess it's caused by bootloader-config, maybe by it calling test_for_bad_drives, which writes to sector 62, matching corruption in 0x38-0x40
