Kernel Panic, Lulu-511-cd won't boot [SOLVED]

#1 Post by thoase »

I downloaded Lulu-511 and burned the iso-file. But when I'm trying to start/boot from the CD, I get these messages:

EXT2-fs (loop1): error: ext2_get_inode: unable to read inodeblock - inode=57346, block=229443

Kernel panic - not syncing: Attemted to kill init!

--

Hmmm, what's wrong.

I usually boot a USB-stick with a 431-version. My idea was to have look at the new PL and then upgrade my USB-stick.

What kind of machine? (e.g. CPU speed, RAM, perhaps even previous OS -- which might tell us approximately how old the hardware is)

I've seen kernel panics occur for many different reasons, but often hardware incompatibility.

It's possible that you may need a "Retro" version (e.g. 4.3.1 Retro), if your machine is quite old.

No problem with PL 4.3 booting from USB and CD!

That should be plenty new for 5.1.1.

I've actually seen quite a few reports of kernel panic for 5.1.1.

Out of curiosity, did you confirm the md5 of your .iso, and did you confirm the burn (I use ImgBurn under Windows for this -- it automatically confirms that the burn matches).

Some burners run way too fast, which results in a bad CD image (I recall several reported problems cleared up when re-burned).

How do I "confirm the md5 of your .iso," as you say? I also use ImgBurn.

But now when I look in my folder Puppy-folder it's only the iso-file. Perhaps I should get the md5-file. But how do I confirm it in ImgBurn?

Imgburn is ok to use, but don't expect a confirmation for md5.
Get the md5sum from the site you downloaded the iso from.
Right click on the iso and you'll have an option to check the md5sum (in puppy) Compare.
If you wan to do this in Windows, there is facility as well, but I think you have to download a kinda md5sum check exe first.

Is it possible to download a torrent-file for the iso-file? Then the checksum should be correct!

Well, if you have a decent link, you'll generally get a good copy also.

Most problems seem to occur during the burn process (but ImgBurn performs a checksum of the ISO image against the burned disk -- so I have to believe that the disk matches the image). One other thing you could do is put the disk in, pull up ImgBurn and have it re-verify the disk against the image (sometimes burned CD disks "go bad" -- i.e. drop bits, sometimes quite quickly -- as they drive the price down, so goes the quality)

It's worth checking the md5, but I'm betting that the problem is a hardware compatibility issue. If the problem persists, I would try 4.3.1 to see if it works.

BTW, I use "md5deep" for my md5 work (does a nice job of traversing folder trees, etc -- I sometimes like to md5 the contents of my drive -- I use it to look for duplicate files).

Can you explain a little more about that?

I use something like:

Code: Select all

md5deep -rz * > tree.md5
sort < tree.md5 > junk.txt
Now the size-sorted file list sits in junk.txt ("-z" gives this), and has an md5, so you know the adjacent files are not only the same size, but truly identical.

I actually tinkered together a Fortran code to do the comparison, and output a list to inspect, before creating a batch file to perform the deletion of duplicates (a little dangerous, BTW -- so I always inspect the list first).

Typically, if I have known duplicate collections, I name the folder that is less ideal (perhaps less-well sorted or renamed, etc) so it appears at the bottom of the directory list, say: "zzzdeletethiscrap"

I generally sort the batch output, and chop all those entries that are not in "zzzdeletethiscrap" (since they must exist in the "master" collection).

Thank you for the quick answer.
In fact asked it as regularly I loose also space in the save file. Some times all of a sudden 1MB some times after a while.

I tried with pfind and date, but I didn't get a good indication.
All the known tricks like SeaMonkey or FireFox settings are done.
Sometimes space is returned after a reboot, sometimes not.

I don't install pet's, but try to install the corresponding program out side the save file. know that sometimes a configuration is added for it /root and this can cause some consummation of the save file, so in that case I check this.

Specially OpenOffice is very keen on this when installing extensions, but I managed to have it all outside the save file.

There are a lot of questions about this subject in the beginners section.

The tool that I wrote isn't a good "beginner" tool.

I primarily use it to purge large duplicates -- for example, multiple copies of ISOs of the various versions of Puppy (I have a number of external drives, and copying things back and forth often results in duplicate collections of crap -- that I forget about, then rediscover, then need to sort...).

Using the stuff above, you will note that a basic pupsave /root/ will contain a number of duplicates -- I would not purge those...

Also, I believe that sort parameters can be adjusted to give an actual sort of size (since standard sort will usually put a file of 9 bytes next to a file of 90000000 bytes)

If you can get a true sort by numerical size, this makes md5deep more useful, as the 100MB files will be sorted together at the bottom of the file (find the "big hitters" right away, without needing a more complex comparison/analysis)

The Puppy reading your pupsave(lupusave) and the file may be corrupt.
Type 'pfix=ram' at the boot prompt.
Or, try LupQ.

pfix=fsck,purge would likely have fixed the problem and kept your savefile. If this happens again try that.

I created a modified boot CD that does this always.

When running a frugal install, I also modify the boot sequence to include this operation on every boot (I'd rather spend the miniscule amount time each boot, than end up with a corrupted pupsave/lupsave).

How is your system installed? And which Puppy version are you running

Are you running a "true" frugal install (requiring no CD), or booting from a CD, with a pupsave and .sfs file?

In the frugal, you modify the boot parameters (which varies, depending on where it is installed -- HDD or Flash)

Changing this for booting from the CD requires a "CD re-master" operation, and alteration of one line of code.
