[Buildroot] Problems with custom config of kernel 2.6.34.1

[Buildroot] Problems with custom config of kernel 2.6.34.1

[Ossy]

Hi mailinglist,

I use the kernel version 2.6.33.6 without any problems. But since I 
updated to the newer version 2.6.34.1 I'm not able to use a custom 
config anymore.

I loaded the old config into the kernel menuconfig and stored it as new 
file linux-2.6.34.1.config. When I launched the overall make process the 
kernel patches were applied fine, but the process runs into text mode 
configuration:

Why is the configuration restarted? The config file was well copied from 
custom directory to output/build/linuxsrc/.config.
So why should I restart configuration in textmode?

Thanks for your help.

Thanks for your report. Could you provide a step-by-step procedure to
reproduce the problem from scratch ?

Thanks,

Isn't that just make oldconfig running? What happens if you press enter to
give the default answer to every question?

I changed the brconfig from kernel 2.6.33.x to 2.6.34.x. I loaded my 
custom kernel configuration into the linux menuconfig and stored it as 
new file. Obviously this not sufficient to migrate from one config 
version to another (I remember once in time it was, maybe 2.4.x days?).

Paul is absolutly right. I gave the default answer to every question 
(only a few...) and wrote this config back to 
mycustomlinuxconf-2.6.34.x.config.

The next time I do not expect to answer questions on the commandline 
during overall make process.

Thanks both for your help.

Marcus

@Thomas: Please note my patch for making u-boot (correcting two typos) 
from 7.7.2010 . The fix is very straight forward (only two changed lines).
