Summary: make oldconfig does not work - user is asked every
config question
Product: Other
Version: 2.5
KernelVersion: 2.6.25.6
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Configuration
AssignedTo: zippel at linux-m68k.org
ReportedBy: tuxman99999 at gmail.com
Latest working kernel version: 2.6.24.7
Earliest failing kernel version: 2.6.25
Distribution: Slackware 12.1
Hardware Environment: Intel P4 (32-bit), 4GB RAM, lots of hard disk space
Software Environment: GCC 4.2.3, GNU Make 3.81
Problem Description: make oldconfig on 2.6.25[.x] appears to work like make
config - user is asked to choose every config option.
Steps to reproduce:
*** VERIFY OLDER VERSION IS NOT BROKEN ***
1. Configure, compile, and install 2.6.24.7 (and modules). .config copied to
/boot along with System.map and vmlinuz. System rebooted to this kernel.
2. Extract 2.6.24.5 tarball. cd into linux-2.6.24.5 and make oldconfig.
Shell reports that .config was created.
3. make menuconfig and visually verify the standard config options I've chosen
for the running 2.6.24.7 are unchanged. Works fine.
*** FAILURE STEPS ***
4. While still running 2.6.24.7, extract 2.6.25.6 from kernel.org tarball.
5. cd into linux-2.6.25.6 and make oldconfig. I'm now asked to choose every
kernel config option beginning with "Prompt for development and/or incomplete
code/drivers (EXPERIMENTAL) [Y/n/?]" etc.
6. After answering 15 or 20 questions, I ctrl-C'ed out of this, realizing that
this is not expected behavior for make oldconfig.
I briefly reported this on LWN (http://lwn.net/Articles/285771/), and Ingo
requested that I report it here.
Please note that I experienced the exact same behavior with 2.6.25.4.
