FEAT: activate software supend in kernel-PAE
Last modified: 2013-01-10 03:00:17 EST
+++ This bug was initially created as a clone of Bug #215396 +++
Description of problem:
No software suspend on RHEL5 PAE kernel too. Can this feature be added to new version of RHEL5?
I tried the same patch on 2.6.18-128.1.10.el5PAE and it can apply successfully. And I test the kernel and it can have suspend to disk with PAE kernel.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
$ cd /boot
$ diff config-2.6.18-1.2798.fc6 config-2.6.18-1.2798.fc6PAE
< # Linux kernel version: 2.6.18-1.2798.fc6
< # Mon Oct 16 14:34:53 2006
> # Linux kernel version: 2.6.18-1.2798.fc6PAE
> # Mon Oct 16 14:51:42 2006
< # CONFIG_HIGHMEM64G is not set
> # CONFIG_HIGHMEM4G is not set
> # CONFIG_NUMA is not set
< # Page alloc debug is incompatible with Software Suspend on i386
No difference in the activation of software suspend since it is not mentioned in
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.

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.

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?

As far as I know, swsusp still doesn't support PAE at 2.6.20.
