System lock-up during boot

[yakker.yak]

Happens some of the time during initial boot-up, with the main progress bar about 1/4 complete.

Checked the RAM via memtest ... ok.

Checked all hardware via Dell diagnostic tools ... all ok.

Are you running a customized version of the kernel? Have you changed anything besides the boot variables?

Would you please post your log files (boot) if you can get them out?

[yakker.yak (yakker-yak)]

Nope, stock Dell Mini kernel and hardware (no mods or upgrades).

There's actually no way to get the boot log out of hardy that I know of [1], although I can provide other logs if needed ...

I guess you could look at /var/log/kern.log at the point where it locks up.

Please find below some of the contents /var/log/kern.log

BTW, also running on the stock bios (A00).

For what it's worth:

During previous lock-ups, a blue, horizontal band, 1 inch high appeared at the top of the screen.

Observed something similar with a recent boot, but the system did not lock-up and finished booting successfully.

[Brian Chidester (brianchidester)]

I have also observed this in Dennis and YM builds in the past.

I have a similar problem with a brand new Mini 9; when I try to look at /var/log/kern.log I get: bash: /var/log/kern.log: Permission denied.

here is a summary of my problem so you see whether you find any similiraty with any of yours:

even after a recent re-installation of the ubuntu 8.04 by certified Dell Ubuntu tecnicians, my brand new Mini 9 does not boot properly. It freezes either on the ubuntu screen at any point on the progress bar or after such screen is finished and it is loading components or starting up. You may get a whole variety of error messages After Ubuntu Screen such as:
blank screen with a blinking cursor
BUG: SOFT LOCKUP - CPU#0 STUCK FOR 11s¨ repeated over and over again
init [1]:segfault at f982c446 eip b7e9b605 esp bfe61868 error 6

This might be a duplicate of that bug: https://bugs.launchpad.net/dell-mini/+bug/300563

Could you try to rule out that the wireless is the problem, by booting with wireless disabled?

[Chris Gregan (cgregan)]

Please confirm this as a new bug by eliminating the possibility of https://bugs.launchpad.net/dell-mini/+bug/300563

[yakker.yak (yakker-yak)]

Have not been able to reproduce this with wireless enabled or disabled.

That is, has not happened to me for a long time. Not sure if related to Jan. 9th, 2009 updates.
