i believe so. as the config file, i grabbed the one for the most
recent ubuntu kernel (2.6.23-32?), copied it to my kernel source dir
as .config, then ran "make oldconfig". and here's the excerpt of the
.config file that was used for the build:
# CONFIG_MULTICORE_RAID456 is not set
# CONFIG_DM_DEBUG is not set
# CONFIG_DM_LOG_USERSPACE is not set
# CONFIG_DM_DELAY is not set
is there anything there that should be "y" instead of "m"?
