I have a Redhat system that was fully working just now.

I started a "yum update" - but decided that the 650Mb of updates probably wasn't a good time to update.  So I typed "N".  I then restarted the system.

I'm now getting a "Kernel Panic - not syncing: attempted to kill init!"

When I go into grub, I can see two options :

Oracle Linux Server-uek (2.6.32-100.34.el6uek.x86_64)
Oracle Linux Server (2.6.32-131.0.15.el6.x86_64)

I've tried booting both to no avail.

My kernel arguments for the second option is :

root (hd0,0)
kernel /vmlinuz-2.6.32-131.0.15.el6.x86_64 ro root=/dev/mapper/vg_ussoadev02-lv_root rd_LVM_LV=vg_ussoadev02/lv_root rd_LVM_LV=vg_ussoadev02/lv_swap rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en.US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us crashkernel=auto rhgb quiet
initrd /initramfs-2.6.32-131.0.15.el6.x86.x86_64.img

Heres the thing - I think when I ran a yum update, it updated the grub.conf to the above version - but its sister (which I didn't run a yum update on) has 2.6.32-100.34.1.el6.x86_64 as its version.

How do I check from grub command line to see what kernel I have available

How to I modify my grub.conf so that I can put it back to the right kernel

I appreciate all the help you can provide with this in advance  !
