Public bug reported:
I have a Dell Studio 15 system which was recently updated to the
Intrepid Ibex Release Candidate release. Since that upgrade
suspend/resume and hibernate/restore have failed shortly following
restore of the graphical interface; often with a black screen but with
the cursor visible, sometimes the bare white square of the password
prompt. The machine will suspend and resume correctly on the latest
kernel from Hardy Heron (2.6.24), but with the exact same Intrepid root
filesystem.
I did some debugging on this. If instead of using the fast-user-
switcher to initiate suspend I sudo to root and run '/etc/acpi/sleep.sh
force' the system suspends and partially resumes. Specificially comes
back up and you can get the X11 console back with ctrl-alt-F7. The
/etc/acpi/sleep.sh has not completed as expected, but is waiting for
'vbetool post' which seems to be running in a tight loop in userspace.
Killing this leads to a hang.
Due to the vbetool interaction and the normal hang with just a cursor
visible, I suspect that this is graphics related. We seem to be using
the i915 module for DRM.
