[Launchpad Bug Tracker <776306@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

i have a new install of natty AMD64, on hp pavilion dv6406nr notebook.

what i tried to do:
---suspend the notebook eg. sudo pm-suspend.
what is expected:
---system suspend.
what happened instead:
---screen blanks for a split second, then shows a screen similar to the one you usually see when booting Ubuntu (the word ubuntu with red dots below). in the same time i hear two 'thud' noises from the speakers. then the system freezes, unable to revive it even with sysrq tools. must do cold reboot.

additional information:
---i was using ubuntu 10.10 i386 until now and didn't have the problem there. therefor this might be a regression, or might be caused by the AMD64 kernel.

i attached some logs from gnome log viewer:
syslog
pm-suspend.log
