Hello,

I am trying to debug a kernel module, which we ported to RHEL5. I find that /boot does not contain a debug vmlinux. Can someone tell me where to locate the debug kernel and how to drop into the debugger or ensure a dump is taken instead of a plain reboot on panic()'ing?
My /boot contains the following files:-
--------------------------------------------
# ls /boot
config-2.6.18-1.2747.el5 message
grub message.ja
initrd-2.6.18-1.2747.el5.img symvers-2.6.18-1.2747.el5.gz
initrd-2.6.18-1.2747.el5kdump.img System.map-2.6.18-1.2747.el5
lost+found vmlinuz-2.6.18-1.2747.el5
-------------------------------------------
Thanks

First RHEL5 is not released yet, so your using the beta2 test release based on your info.

Second, you might want to install the kernel src.rpm as Red Hat does not supply built debug kernel rpms. You might want to install the kerenl-devel rpm packages.

Fine. I am downloading SRPMS-disc1.iso from redhat.
What do I install and how do I ensure that it drops into kdb when the system panics?

So it seems that you have not built a kernel before, judging by this query.

As a suggestion please review;

Building a kernel for the Red Hat family is a little different from the guide, the steps in order are;

make mrproper
make menuconfig
make
make modules_install
make install

Now for about a year now you also have to prep the kernel source as supplied by Red Hat and family, these steps are covered here;

Good luck
