oops in zlib_inflate_fast

[Jarno H.]

Ubuntu was installed to slave hdd. Master contains WXP.
Grub installation also failed.

Traceback (most recent call last):

Same problem has occured on several machines where I have tried to install 20061009 desktop i386.

[Vassilis Pandis (pandisv)]

Marc, please file your problem as a separate issue.

Just spotting interesting spots in the log to facilitate debugging:

[Colin Watson (cjwatson)]

Paul, for your future reference, those errors around the invocation of os-prober are totally irrelevant - they're just artifacts of os-prober trying to mount filesystem as each possible filesystem type in turn. Please ignore them.

[Colin Watson (cjwatson)]

Thanks for your report. This particular error is often due to a faulty CD/DVD disk or drive. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, or to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers). However, the oops recorded in the syslog is a kernel bug.

[Paul Dufresne (paulduf)]

Colin, I am afraid you analyzed Marc's syslog rather than Jarno's one.

[Jarno H. (jarno-hiltunen-saunalahti)]

Don´t if this information helps but I made partition (with GParted) manually when installation crashed.
I tried few times (different partitions) and it crashed everytime. When I used automatic partitioning it pass without any problems.

[Ben Collins (ben-collins)]

I've looked through some stuff, and I'm hoping that squashfs v3.1-r2 (we currently use v3.0) fixes this. It lists a major fix for rare SMP related issues when accessing multiply mounted squashfs filesystems.

It would explain the steady increase in reports, due to a default SMP kernel on the CD, and the increase in dual core CPU's that are out in the wild.

[Simon Law (sfllaw)]

Reproduced on the Vaio:

Here are some attachments.

[Ben Collins (ben-collins)]

Note, this is being worked around in the live-cd's. The actual fixed squashfs will be in the first kernel update.

[Michael Vogt (mvo)]

I tested the squashfs fix and it works for me on my duo core test system.

[Matt Zimmerman (mdz)]

Confirmed here as well; this is worked around in the latest edgy CD builds.

[Paul Dufresne (paulduf)]

I am quite lost by you developers on this bug.

First, no one seems to have comment on the fact that original poster have nothing to do (as far as I see) related to kernel bug.
In fact, I see no usefull errors information in Jarno files except maybe:
Oct 10 16:01:24 ubuntu grub-installer: The file /boot/grub/stage1 not read correctly.
Oct 10 16:01:24 ubuntu grub-installer: error: Running 'grub-install --no-floppy "(hd0)"' failed.
at the end of syslog.

Then, I can only guess you have confirmed Marc Tardif bug about zlib oops that have followed the zlib error:

I believe bug #67874 to be a duplicate too.

Note that there exist a bug reporting freeze on Dual Core on 6.10.
See bug #68612
