Shang Wu, thank you for reporting this and helping make Ubuntu better.
This bug was reported a while ago and there hasn't been any activity in
it recently. We were wondering if this is still an issue? If so, could
you please provide the information following
https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume ? As well,
can you try with the latest development release of Ubuntu? ISO CD images
are available from http://cdimage.ubuntu.com/releases/ . However, note
you can only test Suspend, not Hibernate, when using a LiveCD. If the
issue remains, run the following command in the development release from
a Terminal (Applications-Accessories-Terminal) as it will
automatically gather and attach updated debug information to this
report.
apport-collect -p linux BUGNUMBER
Additionally, if you could try to reproduce this with the upstream
mainline kernel that would be great. It will allow additional upstream
developers to examine the issue. Refer to
https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the
upstream kernel, please remove the 'needs-upstream-testing' tag. This
can be done by clicking on the yellow pencil icon next to the tag
located at the bottom of the bug description and deleting the 'needs-
upstream-testing' text.
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.
If you are unable to test the mainline kernel, for example it will not
boot, please add the tag: 'kernel-unable-to-test-upstream'.
Please let us know your results. Thanks in advance.
