[Bug 172937] Re: SQUASHFS error while booting from live cd

[cornware-cjp]

I have a solution to this problem, that helped me, and may also help
other people for who the above solutions didn't work:

Use the Netboot installer!!

The netboot installer is a lot smaller than the live CD, because it
doesn't contain any packages: instead, it downloads these from the
Internet while installing. This will help you if this problem is caused
somehow by errors on the CD-R: the probability that the netboot
installer hits one of these errors is lower, because of the smaller size
of the netboot image. It worked for me!

Now that I have 10.04 on my nx6110(*), I used it to burn the live CD
again. I used Brasero with 4x speed (the lowest possible), and I used a
CD-R from a different series. To my surprise, the CD self-check didn't
report ANY errors! So I booted the CD, which it did (it still mentioned
filesystem problems in the boot messages, but they didn't seem to be a
problem). I did not try the installer, because I didn't want to disturb
my current 10.04 installation.

That made me wonder whether my first series of CD-Rs was guilty of the
problem. So, I took another CD-R from the old series, and made another
live-CD burn with EXACTLY the same hardware, software and settings, and
the result was: a CD with errors!

My conclusion: in my case, the problem was a bad series of CD-Rs. This
was further confirmed by comparing the files on the failed CD-Rs with
the files in the .iso image: there were differences.

My BAD series is:
Maxell CD-R "up to 52x" 20 pack 5mm case 700MB
Barcode 4 902580 349554

My GOOD series is:
Sony CD-R 700MB x30 (1x - 48x compatible)
Barcode 4 901780 808465

At least I didn't waste half a dozen of GOOD CD-Rs on this issue! :-)

(*) I forgot to mention: I installed an extra 1024MiB of RAM. However,
Memtest86 doesn't report any problems.
