I'd also recommend just > trying a standard prebuilt Debian kernel. > http://packages.debian.org/squeeze/linux-image-2.6.30-1-amd64 As we commented in this [1] thread, the problem was due to a patch that Debian developers have applied to stock kernels enabling only libata for the systems having a SATA controller. For that reason the Debian stock kernel saw disks as hdX and kernels 2.6.31.2 and 2.6.30.3 compiled by myself saw disks like sdX. After booting, with 2.6.3x, no longer panic is observed when restituting the memory to its initial value. Thanks for your reply.
