BUG: unable to handle kernel NULL pointer dereference at (null)

[sadnessi]

i update the kernel (automatically with update manager) and activate the drivers of broadcom (wireless) and nVidia (185, for display) when i restart, nothing happend after the image of teh bios, the display never change (always dark)....... and i push the shutdown button (i was bored.....).

then the list of kernels appears ths next time that i restart... and select the previous kernel of installation (there were 2.30.5 and 2.30.6 as example, so i select 2.30.5)

ok.... that was my first bug.... but this is another thing.... y install full and clean ubuntu 10.04 in my computer and installed (or activated) the druvers for my display... then i hbernate my computer, but whenm i resumed it.... that hapend... no pass more of the dark screen after the bios messages (hp.. bios..... you know...) and i can say that hp pavilion dv9628nr cannot hibernate with ubuntu guest SO.... but with this new version (10.04) the shutdown and power on is faster than the last one.... so... thanks to post....

[sadnessi (sadnessi)]

i am again..... you may say: i will have nightmares....!.. anyway updating info....
this problem is maybe caused by too memory.... i mean:
this computer don't support the hibernation in windows xp because have too fisical memory (2 GB) so i need a fix package to "repair" the problem of too memory and can hibernate; in ubuntu may be the same problem.... in the last distro that i install (Ubuntu 9.10) i had 2GB of fisical memory and other 4GB of swap partition (6 GB in total); so maybe is the same problem... "is too Memory", now in this distro (ubuntu 10.04) i only have a swap partition of 1GB and the normal memory of 2GB (fisical,3 GB in total) and yesterday in the night i put to hibernate the computer (i say: "WTF... it doesn't matter") and when i resume.. did it, the computer resumed without problems......

so tahnkyou to helpme....... and listened to me...!!!

Hi sadnessi,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you 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 562760

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.
