Confirm by installing kernels

No this bug using:
[DIR] v2.6.36.4-natty/ 18-Feb-2011 11:34 -
This bug starts in every next kernel since:
[DIR] v2.6.37-natty/ 05-Jan-2011 11:23 -

take files starting with linux-image-*** ending with *** your architecture i386.deb or amd64.deb
then install them and restart in each kernel.
For my Emachines E525 this is how i wrote.
