Answering myself (and providing info that can be Googled): > I wanted to boot a recent kernel on an old machine and failed. > The last kernel that worked was 2.6.27. > What goes wrong is that the disks are no longer detected on 2.6.28. A typical error would be Cannot open root device 342 or unknown block (3,66) Reading the code shows that the default probing is no longer done. Editing ./drivers/ide/ide-generic.c and changing -static int probe_mask; +static int probe_mask = 3; returns my disks to life, and this old machine boots again.
