Thank you very much for the link.. I have built a new bootable kernel 2.6.9-67 on my machine. However I still have a problem :(

During the installation at "make menuconfig" stage after "make oldconfig" I have added the generic HDLC package with synchronous PPP support and saved the new config then run

rpmbuild -bb --target=`uname -m` kernel-2.6.spec 2> build-err.log | tee build-out.log.

After reboot, I rechecked the menuconfig to make sure that the HDLC setting is there. I am not sure if this setting took effect or I have to make modules or build something else. So how would I know that the HDLC package is availalbe and built in?

To elaborate more on the reasons behind this HDLC package, I am trying to build a device driver that asks for HDLC support. upon building the driver, I get the following warnings:

 Building modules, stage 2.
 MODPOST
*** Warning: "unregister_hdlc_device" [/home/DS3/wanPTMC-256T3_2_0B/driver/wan256t3.ko] undefined! *** Warning: "hdlc_ioctl" [/home/DS3/wanPTMC-256T3_2_0B/driver/wan256t3.ko] undefined! *** Warning: "hdlc_open" [/home/DS3/wanPTMC-256T3_2_0B/driver/wan256t3.ko] undefined! *** Warning: "register_hdlc_device" [/home/DS3/wanPTMC-256T3_2_0B/driver/wan256t3.ko] undefined! *** Warning: "hdlc_close" [/home/DS3/wanPTMC-256T3_2_0B/driver/wan256t3.ko] undefined! *** Warning: "alloc_hdlcdev" [/home/DS3/wanPTMC-256T3_2_0B/driver/wan256t3.ko] undefined!

Therefore, I am suspecting that I need the HDLC package available. I would be extremely thankful for anybody who can help me in this problem. Am I going into the wrong direction?

Hello folks,


Hi. It is request for it to add this in kernel for centosplus, look at this: http://bugs.centos.org/view.php?id=3019


I am trying to add HDLC module support in the menuconfig. However, I am facing difficulties in rebuilding the kernel and modules. My main objective is to get the HDLC supported in kernel 2.6.9. I have a CentOS 4.4 with kernel 2.6.9.42. I need help in finding the best way to add the HDLC support whether through getting an RPM package for it or refering me to the right procedure in rebuilding the kernel.

Thank you very much in advance for your help.


No problem.



That request was for CentOS-5, not CentOS-4 :D


? I can see: Category: [CentOS-4] kernel-centosplus My request was exactly for centos 4 branch, but for 5 is good too. So, can i count for You to make it posible in centos4 to support hdlc ?


HDLC was added to the CentOS-5 plus kernel for the latest version.

Sorry about the top posting :(

After reconfiguring the menuconfig to enable the HDLC suport package (under device drivers). I have tried also do:

modinfo hdlc

but i did not get any info in return... Also I have tried :

lsmod

to check for hdlc module but I could not find it... I guess I am missing something to activate my new settings in the menuconfig. Is there a way to verify that my new settings active!! Does any body know about the HDLC modules loading in the 2.6.9. Please advise. And thank you all for your help.
As i remember: hdlc is build not as module, it is core kernel module, not module to load by modprobe - so in menuconfig is [*] with hdlc not [M] as module.

But maybe i'm wrong.
