Hi,
I´m with a kernel panic error in a very stable server (HP ML110).
edit: add screens to ilustrate the problem: (I´ll remove them later)
Kernel panic with 2.6.32-754-9.1

I´ll had to remove the first 2 entries to avoid problems (last reboots , I´ve to choose manually the last option) and also will remove kernel package because all RPM keep only 3 versions ... so I´m about to loose last option and it ´s the only working.
I have these packages installed:
[root@andorinha ~]# rpm -qa|grep kernel
kernel-2.6.32-754.9.1.el6.x86_64
kernel-devel-2.6.32-754.6.3.el6.x86_64
kernel-2.6.32-754.10.1.el6.x86_64
dracut-kernel-004-411.el6.noarch
kernel-2.6.32-754.6.3.el6.x86_64
kernel-firmware-2.6.32-754.10.1.el6.noarch
kernel-headers-2.6.32-754.10.1.el6.x86_64
kernel-devel-2.6.32-754.9.1.el6.x86_64
kernel-devel-2.6.32-754.10.1.el6.x86_64
and now removindo olde kernels -9 (to keep on safe side and avoid any other RPM package remove my working kernel package)
[root@andorinha ~]# rpm -e kernel-devel-2.6.32-754.9.1.el6.x86_64 kernel-2.6.32-754.9.1.el6.x86_64

and verifying the remaining kernel packages:
[root@andorinha ~]# rpm -qa|grep kernel
kernel-devel-2.6.32-754.6.3.el6.x86_64
kernel-2.6.32-754.10.1.el6.x86_64

kernel-headers-2.6.32-754.10.1.el6.x86_64
kernel-devel-2.6.32-754.10.1.el6.x86_64
and now updating menu.lst

Note I´ve increased timeout to allow user to see menu and choose right one (the oldest) if necessary and removed the 754-9 option, because I removed it as package using RPM.
Anyone had same problem ?
How can I diagnose the kernel panic error ?
Thanks,
Jáder
