Hi!

I am a new user and I am trying to boot 6.5 (x86_64) from a usb created with unetbootin. My computer has a haswell i5 processor with intel hd4600. This is the message I get when panic occurs:


i915 0000:00:02.0: More than 8 outputs detected


Kernel panic - not syncing: Attempt to kill init!

pid:1,comm: init Not tainted 2.6.32-431.1.2.0.1.e16.x86_64#1

Call trace:

drm_kms_helper: panic occurred, switching back to text console



Any help would be gratefully received and please keep it simple as I am not yet an experienced user. Thank you!

Hello Martin,

Can you try to create the usb stick using DD directly instead of Unetbootin and see if that works?

Unfortunately, it doesn't. I still get the same error message.

Right, sorry about that.

While at boot loader stage, can you press TAB and edit the kernel entry so that you can remove "rhgb" and "silent" parameters? This should provide us with some more information hopefully.

Ok, I did as you asked and immediately before the above warning is this:


dracut warning: No root device "block:/dev/mapper/live-rw" found

dracut warning: Boot has failed. To debug this issue add "rdshell" to the kernel command line.

dracut warning: signal caught!

dracut warning: Boot has failed. To debug this issue add "rdshell" to the kernel command line.

This is weird, it doesn't seem to see the live media.
Can you verify the md5sum of your ISO/stick to see if it matches the one here http://li.nux.ro/download/ISO/ ?

Additionally, can you give the 32bit ISO a try, it contains also the kernel-ml (kernel main line, 3.x) which may boot: http://li.nux.ro/download/ISO/Stella6.5_i386.3.iso

Also, what kind of hardware do you have exactly?

The md5sums match just fine. The 32 bit version caused kernel panic too with this additional message:

[drm: i95_write32] *error* unknow unclaimed register before writing to c5100

With the 32bit ISO have you also tried the second kernel? That's the kernel-ml, I need to label them properly.

I downloaded the 32-bit version you linked to above. Booting from the first entry produced panic and the message I give above. Booting the second entry (which has the same name?) causes panic and gives a longer message:

FATAL: module scsi_wait_scan not found

Problem solved. It booted fine from a dvd Rolling Eyes

Looking through the Centos forums, it would seem a few people have had this problem but I couldn't see any solutions. First time I have ever encountered something like this.

Ok, definitely weird, but something to remember for the future. Perhaps your USB was faulty..
