Kernal Failure on Fedora 11.
 

Hi,
I am using HP laptop. I have installed Fedora 11 on my system. Two kernels have been installed on my system and are:

2.6.30.5-43.fc11.i686.PAE
2.6.29.4-167.fc11.i686.PAE

when i am booting my system with Kernel 2.6.30.5-43.fc11.i686.PAE system is generating some noise and after login a popup window is coming up showing the message
"Your system has Kernel Failure"
and this is what the failure is:


Kernel failure message 1:

---------------------------------
While the second when i am booting my system with kernel 2.6.29.4-167.fc11.i686.PAE i am not getting any such kind of error messages.

So my question is why two kernels have been installed and how to fix the error with kernel 2.6.30.5-43.fc11.i686.PAE.

I am new to Linux so don't know what other details are required to be posted along with this. Please let me know if any other details are required.

Any help/suggestion will be highly appreciated.

kernels
 

-43 is an old kernel but there if -167 fails, I assume the later is working, so don't worry about the former, it is only a backup.

Fred.

When originally i installed the fedora 11 i had just one kernel, I do not remember which one of these two kernels was installed at that time. After Yum updates the second kernel got installed.

Now the situation is system is booting by default with kernel
2.6.30.5-43.fc11.i686.PAE
which is having the problem. So is there any way by which i can uninstall this kernel so that i have just one kernel and the system will boot with that kernel.

Or if this is not possbile then can i change the default kernel with which system will boot.If yes, then please let me know how can i do that.

fc-11 installs with 2.6.29.4-167.fc11.i686.PAE
if you do yum install kernel kernel-devel it will install the latest: 2.6.29.4-167.fc11.i686.PAE

i actually had the same issue with 2.6.29.4-167.fc11.i586 but i just ignored it.

if you want to boot a different kernel, then backup and modify /boot/grub/grub.conf

So as suggested by you if i am doing yum install kernel kernel-devel for kernel 2.6.29.4-167.fc11.i686.PAE will it remove the other kernel ?
After booting the system second time i am seeing the error message "Your system has Kernel Failure" even when i am booting the system with 2.6.29.4-167.fc11.i686.PAE kernel.

So i just want to remove the second kernel from my system.
Is there any method to remove the second kernel completely from the system ?

can you please post the outputs of:

I don't know what to tell you, new kernels are, well, new. Just use the old one for now, they don't go truly obsolete fast. Just upgrade to the new release.

change default=0 to default=1
