Bug Description

Suspend to RAM on my Fujitsu P1510D doesn't suspend.

It blanks the screen, but the power LED doesn't blink.
I can't get to a virtual terminal.

Rebooting results in:
Error 16: Incorrect filesystem structure

After I choose "rescue mode" it returns to normal.

This is not the same as these bug reports because
60243: Power LED doesn't blink
81548: No "Linu", and it doesn't show anything at all
97484: Unable to access VT
104185: Not possible to restart system

The site says:
"I need /etc/acpi/resume.d/99-undim.sh or the backlight will stay off"

and makes reference to the attached file:

I can confirm the above file works!

SImply download and move it to /etc/acpi/resume.d/
Then sudo chown a+x /etc/acpi/resume.d/99-undim.sh
and sudo chmod root:root /etc/acpi/resume.d/99-undim.sh

It will work straight away! :-)

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Please reopen this if it is still an issue in the actively developed pre-release of Jaunty Jackalope 9.04 - http://cdimage.ubuntu.com/releases/jaunty . To reopen the bug report simply change the Status of the "linux" task back to "New".
