hi, i tried compiling linux 2.6.25.4 in my VL5.8 (guest OS in virtual box)

i have compiled the 2.6.25.4 kernel already and have loaded it in grub for a test .. BUT since im getting a problem I HAVE tried turning back to the original kernel.. BUT WHY eventhough i have commented out the test kernel in menu.lst still the new kernel is sitll loading ??

details :


#TEST KERNEL

#title Test Kernel
# root (hd0, 4)
# kernel /boot/bzImage-2.6.25.4 root=/dev/hda5 ro vga=normal
# initrd /boot/initrd.img-2.6.25.4


BUT when i check uname -a

Linux vector.linux.net 2.6.25.4




please help. .     thanks

how did you install the kernel?

[icedtea]

i have downloaded it from the site.. uncompressed the file to /usr/src

1, make menuconfig

then :

Root device is (3, 5)
Setup is 11096 bytes (padded to 11264 bytes).
System is 2712 kB
Kernel: arch/x86/boot/bzImage is ready  (#1)

_______________________________________

btw i have resolved my problem.. (sorry since its my first time to compile a kernel )

here it goes


1. my EDITED grub/menu.lst

# Start GRUB global section
timeout 60
default 0
splashimage=(hd0,4)/boot/bitmap/boot.xpm
#color light-gray/blue black/light-gray
# End GRUB global section
# Linux bootable partition config begins
  title Linux on (/dev/hda5)
  root (hd0,4)
  kernel /boot/vmlinuz-2.6.20.3 root=/dev/hda5 ro vga=normal
# Linux bootable partition config ends

#TEST KERNEL

 title Test Kernel (/dev/hda5)
  root (hd0,4)
  kernel /boot/bzImage-2.6.25.4 root=/dev/hda5 ro vga=normal
 #initrd /boot/initrd.img-2.6.25.4


___________________________________________


the reason ON WHY i was not able to roll back at my previous kernel is because of this :

# Linux bootable partition config begins
  title Linux on (/dev/hda5)
  root (hd0,4)
  kernel /boot/vmlinuz-2.6.20.3 root=/dev/hda5 ro vga=normal
# Linux bootable partition config ends

the KERNEL loaded is vmlinuz and NOT the one posted above..
i think vmlinuz was created since i have compiled my kernel ...

the reason for me knowing this is because of the timestamp :

root:# ls -l vm*
-rw-r--r-- 1 root root 2788076 2008-06-03 18:25 vmlinuz
-rw-r--r-- 1 root root 3937096 2007-05-13 11:38 vmlinuz-2.6.20.3
-rw-r--r-- 1 root root 2788076 2008-06-03 17:48 vmlinuz.old


so i just used the ORIG vmlinuz-2.6.20.3

and now i can load my previous kernel..


thanks


NOW my problem  is upon using the TEST KERNEL.. my firewall is NOT working including the internet..  everytime i start  the firwall it will say something like :

your iptables or kernel must be upgraded.. .

question: CAN I STILL MODIFY my test kernel then re-compile it? (to be able to somehow figure out the firewall problem )

you can change the options in the kernel config and recompile it as many times as you want.
