Did you use the 'huge' or 'generic' config as template?
I have tried 3.6.8 with the huge config and trying to go easy on myself ...
yes "" | make oldconfig
I found that DLM gave me errors (CONFIG_GFS2_FS_LOCKING_DLM=y) so had to change it to 'n'.
It then compiled with no (serious) errors, but I can't run it - alas - the infamous "failed to mount filesystem on ..."
I tried a good oldfashioned 'make oldconfig' but was asked wayyy too many questions for my simple mind.
If your config-3.6.7 is 32-bits, would you mind terribly posting it somewhere?
Thanks in advance.
