Ubuntu 10.04 i386 live CD does not boot

Ok talking to the reporter on IRC this is the i386 live CD as at 07-apr-2010.

As we see ureadahead-other running we have at least got out of the kernel into userspace before the issue appeared. The BUG: lines should include a stack trace and that trace would give us some clue as to the source of the soft-lockup. You may be able to boot the machine to single user (using single on the kernel command line) and be able to see the whole trace with the dmesg command. Getting a photo or similar of that and attaching it to the bug would be helpful. Right now its impossible to know what the cause is.

After some work on IRC, I can confirm that init=/bin/bash in syslinux does boot to grub, but once

exec init

is executed, it freeze instantanly, with the trace found above. DMesg looked clean before the freez. It look like sreadahead just fail badly.

The 10.04 i386 rc does not boot on my Asus AliveSata2-GLAN/A/ASR AMD64x2 4200+. Disk just spins a couple of seconds then goes into 9.10 boot.

Hi Elv13,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/ . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 557351

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I am unable to boot Ubuntu 10.04 final release from Live CD on my Dell Optiplex 380 and Precision M4300. The latter one runs Ubuntu 9.10 well. ...never tried the Optiplex with Ubuntu.

The screen just freezes with the image attached.

...read some people having the same problem.

Hi,
I also have the same problem that "Kyty", already tested in 32-bit and 64-bit and both have this problem.
My computer is:
Motherboard ASUS P5K SE
Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz
NVIDIA GeForce 8600 GT
Please help me.

I had an incomplete ISO download. Now it works.

Kyty,

can you please tell more about complete and incomplete ISO download. I downloaded twice from http://www.ubuntu.com/desktop/get-ubuntu/download. Both files have a size of 699.4 MB. I burn iso file to a disc using Brasero Disc Burner, no error was reported.

When I tried out the live CDs, they friezed on a screen as shown in your "kyty wrote on 2010-05-20:". While Ubuntu 9.04 got something like checksum, I did not find any for 10.04.

I am using Notebook Compaq Presario A900. By the way, my computer is running Ubuntu 10.04 , dual boot Windows XP, upgraded online from Ubuntu 9.10 without problem.

Somebody please advise. Thanks

Toni,

I twice downloaded the ISO via HTTP. Both times were incomplete -- the connection was lost and files ended up less than 699 MB.

Then I used torrent and it worked. http://www.ubuntu.com/desktop/get-ubuntu/alternative-download
