If you noticed just now, my website was inaccessible around 2 hours.

Reason: I switched the main kernel to the later release and missed to include the kernel headers (which is -by default- left out to keep the system small)

Guess what? Right after bootup, several modules failed! ... and to make it more worrying is that the kernel hit panic button by refusing to boot, even with a 'nice' message to copy certain kernel panic dump upon booting -> perfect!

I was planning to do disaster recovery from the backup and while waiting for the proper boot CD to be downloaded from the Internent, I tried several old boot CDs in order to restore the last-known-state.

Magic happened! Right after mounting the main partition, none of the commandd worked! -> great!

So, what's next? Disaster recovery? My gut feeling said to try check the disk partition. So, after several weird result after mounting the partition, I came accross kubuntu CD that I have, booted it up and use the live-CD method.

Once inside the live GUI, I qickly try to mount the parition again. I didn't put much hope as the other two rescue CD version failed to do anything further after mounting. Guess what? It worked with kubuntu!!! Quickly after mounting the partition, I dismount it immediately for disk check, repair it and do the same thing for the other partition that holds the primary backup (the DR backup is not in this partition, but if this partition survived, at least I don't have to do full DR). No problem found in the second partition.

Now, the moment of truth: is the kernel panic really because of corrupted kernel, missing libraries, or something else?

Restarting the system brings me back to the nice 'welcome' login without a fuss of kernel panic whatsoever -> yay!

Conclusion: the disk was corrupted during the reboot. Honestly, the system was a little bit stuck when I tried to rebooted it, and turned out that this is the result

... and now, you can also see the updated blog of mine, which shows that the system is running fine -> ha!
