Bug Description

This is kinda error I receive when I boot Pentium III 1.0 GHz 512 MB RAM system from Ubuntu 7.04 CD. After selecting Start or Install option, I get a command prompt message and then an Exception with EMask of 0xff and something about initramfs. Can you please tell me what is the problem with this thing. Thank you.

Thank you for taking the time to report this bug and helping to make Ubuntu better.
The message 'bin/sh cannnot access tty; Job control turned off' should be ignore.
I did fill a bug about it: bug #129612.
Please take the time to take a pen and a paper and to note message errors seen,
and then report them back here.

The error we care is the one BEFORE the command prompt.
But that you get one AFTER is also intriguing, if you could give more info, like the 'something' about initramfs, it would be nice.

The issue that you reported is one that should be reproducable with the
live environment of the Desktop CD of the development release - Gutsy
Gibbon. It would help us greatly if you could test with it so we can
work on getting it fixed in the actively developed kernel. You can find
out more about the development release at http://www.ubuntu.com/testing/

A new beta version, Tribe 4, should get out in the next 24 hours.
I think it would be even more valuable for us to know if this still happen with it,
than answering my previous post. Still, feel free to answer previous post!

/casper.log after "can't access tty; job control turned off" Edit (5.0 KiB, text/plain)

Booting the Ubuntu 7.04 i386 CD on a desktop system with an Albatron KX400+ motherboard and an AMD Athlon (tm) XP CPU clocked at 1466MHz, with 768MB RAM, I get the following text after a minute or so of the Ubuntu shuttle:

BusyBox v1.1.3 (Debian 1:1.1.3-3ubuntu3) Built-in shell (ash)
Enter 'help' for a list of built-in commands

/bin/sh: can't access tty; job control turned off
(initramfs) _

(I copied this from a digital photo; I hope it's accurate.)

There's a /var but no /var/log and therefore no /var/log/casper.log, but there is a /casper.log. There's no /etc/fstab, but I managed to mount a USB CF-card reader and copy /casper.log to it. It's attached.

I don't know why there are repeated messages about not being able to open /dev/fd0 and /dev/fd1; I was able to mount and read a floppy disk. Unfortunately I don't know enough about *N*X to figure out how to try to mount the CD-ROM.

Is there a release of Ubuntu that won't give me this headache?

Martin, unless you also have the message with an Exception EMask of 0xff, I suppose your problem is a different one. So please open a new bug, and post it's number here so as having me take a look.
