Package: linux-source-2.6.35
Version: 2.6.35-1~experimental.3
Severity: normal

I tested kernel 2.6.36 and found that hibernation failed when the
process was attempting to suspend operation of CPU's 1,2 and 3.

I verified that hiberation proceeds if CPU's 1.2 and 3 are manually
suspended prior to requesting that part of the hibernation (freezing)
test.

Tested 2.6.35 - same result.

The test works for 2.6.34, thus the regression appears to be in
linux-source-2.6.35

'test' - refers to the procedures set out in source/Documentaion/power
basic.pm.debugging.txt
