Bug#677472: More information

["Octavio Alvarez" <alvarezp@alvarezp.com>]

Under normal circumstances the system simply does not suspend. It appears  
to go all the way to suspension (screen off, disks off, etc.) but when it  
appears that it is going to go off, something prevents it. System doesn't  
hang, it just fails at the very last moment of suspension.

I tried debugging using pm_test. I set it to "core" but suspend_stats  
doesn't catch anything:

# cat /sys/kernel/debug/suspend_stats
success: 12
fail: 0
failed_freeze: 0
failed_prepare: 0
failed_suspend: 0
failed_suspend_noirq: 0
failed_resume: 0
failed_resume_noirq: 0
failures:
  last_failed_dev:	
			
  last_failed_errno:	0
			0
  last_failed_step:	

Even with pm_test set to "none", suspend_stats increases the "success"  
value.

As I said earlier, removing ohci_hcd lets suspend work again.

Also, I didn't find anything wrong in /var/log/pm-suspend.log. I may paste  
it in another message if you want because it's 4000 lines long.
