Post subject:  Kernel panic
I was moving cables around in my cabinet and heard a "bad" noise through my speakers. The system was on and I had a recording paused. The "bad" noise was a sort of hum and crackle. I'm guessing that is the source of my problem but I'm not sure how to best proceed.

Noticed the first problem when I tried to unpause my recording and it wouldn't. Rebooted, went back to watch the same recording and hung again. Rebooted, got to the main menu before hanging. Now every reboot dies before KnoppMyth starts.

I've rebooted multiple times and lots of messages, I'll try to type some that I wrote down. The first message was just trying to boot the system. The second and third was when I tried booting from the KnoppMyth R5F27 CD:

------------------------------------------------------------------------
booting the kernel:
mount failed for selinuxfs on /selinux: No such file or directory
------------------------------------------------------------------------
...
EIP: [<c01b19a8>] sysfs_dirent_exist+0x48/0x70 SS:ESP 0068: dff83e40
<0> Kernel panic - not syncing: Attempted to kill init!

.
EIP: [<c017740e>] cache_flusharray+0x8e/0xc0 SS:ESP 0068:dfe99d5c
Kernel panic: Fatal exception in interrupt
------------------------------------------------------------------------

Any ideas or tips on troubleshooting this? I'm guessing that sound was some sort of short somewhere.

When you say cabinet, Are you referring to your computer case being open and moving cables around inside it, or are you talking about moving cables that are all external to your computer?

If you were working inside the computer, could a fan have come loose or a cable is stalling the fan blades or a heatsink come loose on the cpu or mb chipset, and you are having a heat problem? Did you try leaving the computer off for a long while to cool down and then try booting it cold? Are the hard drive and CD rom cables tight on both ends?

Hum and crackle sound like the audio cables got bumped.

If you were working outside the computer, could you have moved a cable that connects to an I/O card in the computer and jarred it loose inside? Have you tried removing and re-seating each card? including the sound card?

I was talking external to the computer. I went ahead and opened up the case and reseated cards, connections, memory, whatever I could. I was able to boot up and now seem to be working.

The problem actually began last evening so the computer had been off overnight before I tried and failed again this moring.

Thanks, I was really not too happy this morning but am feeling a lot better right about now.
