Here we go.

I was wrong earlier: the atomic restore goes ok but the cache restore
goes bad. It's probably the same problem as the vanilla kernel (except
that it crashes before overwriting my / partition).
The .config and the lspci are attached. The disk controller is the SATA link
from the SB600 (driver ahci). The kernel version seems irrelevant (problem
occurs with at least 2.6.18, 21, 22 and 25)
Thanks for any help,
