- NOTE (an uppercase one, indeed): there are a lot of menuconfig changes in
here which break `make oldconfig' badly. If you grab an old .config and run
`make oldconfig', your kernel probably won't work. I lost useful things
like CONFIG_BLK_DEV and the whole SCSI system, because they were added after
I generated my .config.

So save yourself some hassle and check your .config carefully before
building this kernel. Make sure that everything you need is still enabled.

I found that manually adding "CONFIG_BLK_DEV=y" to the .config before
running oldconfig saved a large number of config items from getting lost.

On the one ppc64 machine I have to test on for memoryless nodes, I
found I had to add back in CONFIG_BLK_DEV=y and
CONFIG_SCSI_LOWLEVEL=y. Just for reference as other folks pull out
their hair.

Those menuconfig changes have been a huge pain.

Yes.

Thanks,
Nish
