Description of problem:



Version-Release number of selected component (if applicable):


How reproducible:

always

Steps to Reproduce:

$ cd /boot  
$ diff config-2.6.18-1.2798.fc6 config-2.6.18-1.2798.fc6PAE

Actual results:
[...]
229,230d230
< CONFIG_SOFTWARE_SUSPEND=y
< CONFIG_PM_STD_PARTITION=""
[...]

Expected results:

No difference in the activation of software suspend since it is not mentioned in 
http://fedora.redhat.com/docs/release-notes/fc6/en_US/sn-Kernel.html#id2840748

Additional info:

For notebook users pae may not be imported but the No eXecute feature and the
suspend feature of the kernel are. For this reason both features should be
accessable or at least it should be proper documented.
Comment 1 Dave Jones 2006-11-24 22:19:16 EST
PAE & suspend are incompatible in 2.6.18.  I believe this has been fixed for
2.6.19, so when I backport that after its release, this should be fixed hopefully.
Comment 2 Mihai Harpau 2007-01-12 07:04:29 EST
Situation is the same in kernel-PAE-2.6.19-1.2895.fc6 from updates-testing:
software suspend is disabled. Any reason for not activate it?
Comment 3 Nigel Cunningham 2007-02-20 16:56:12 EST
As far as I know, swsusp still doesn't support PAE at 2.6.20.

Comment 5 Dave Jones 2007-03-19 16:45:10 EDT
Indeed, it should be present in the current builds..
