mk_kernel : "dev_config" error (hpux 11.23)

Any clue why I'm getting the error below?
I would greatly appreciate any help. HP ITRC is already engaged since this morning but until now I haven't got any resolution. I'm wondering if anybody out there got an idea on how to fix this. Thanks in advance.

This is my system:

HPUX11i-OE-Ent B.11.23.0706 HP-UX Enterprise Operating Environment Component

ia64 hp server rx2660

------------------------------------------
ERROR MESSAGE:
------------------------------------------

root/stand# mk_kernel -o /stand/vmunix
ERROR: The configuration is supposed to include a module 'dev_config',
which is not available because its file has been removed from
disk.

----------------------------------------

Does anybody know what file is associated with "dev_config" module? I can't find the file itself (dev_module) in any of my working system running on the similar hardware and OS version.

Here are my kconfig that might help in finding what is wrong with my system

# kconfig

Any clue or suggestions anybody can give will be very much appreciated.
Thank you very much.

Thanks to ITRC
Just got this error fixed and I wanted to share this info to everybody:
What FIX it?
Running update-ux in preview mode and NOT saving anything when you exit. :slight_smile:
update-ux installs OE executables temporarily in:
/var/adm/sw/sbin
/var/adm/sw/lbin
/usr/lbin/sw/bin
links the following executable files in /usr/sbin to /usr/adm/sw/sbin
-----------
sd
swacl
swagentd
swconfig
swcopy
swinstall
swjob
swlist
swmodify
swpackage
swreg
swremove
swverify
------------
update-ux cleans up its trashes when you exit without saving anything :slight_smile:
This command below helped in tracing out the culprit "kconfig" in /usr/lbin/sw/bin when I ran mk_kernel
# ./tusc �o hp.txt mk_kernel �v �s /stand/system
grep kconfig hp.txt
---------------
stat("/usr/lbin/sw/bin/kconfig", 0x7fffe230) .......................................................................................... = 0

Thanks for the information!
