Well, I've booted up my Libretto 70ct and and busy installing -current (hopefully it will be finished by the weekend ;~>) But my recollection of the issue having built a lot of kernels since 4.4 when I first encountered the issue is that it has more to do with the fact the Libretto only has 16 Mb of RAM, and if the kernel is bigger than 6.5 Mb it appears to run out of memory. I've not invested much effort in solving this recently - partly as I knew that I'm not ever going to upgrade it to 32Mb of RAM - and as Nick hinted this will be come a limiting factor. But you've motivated me to have another go at fixing my little old Libretto 70CT :~) Fred
