Bug Description
Hi.
For a long time now, possibly years, I have been having issues suspending my computer to RAM. This is what happens:
- I use a dbus command to attempt to suspend
- (it sounds like) The disks spin down almost immediately
- The screen and fans stay on for about 60 seconds
Then either:
- The computer suspends
OR
- The computer resumes immediately
I have no idea why this happens. I know that it does not happen with Windows Vista on the same machine, but that it does happen with other linux distros (well, at least Arch). I think it started around the time the 3.0 kernel version started getting adopted (give or take an Ubuntu release), but I do not know if that is accurate, let alone relevant.
I posted this as a question at askubuntu:
http://
and was directed here.
I am currently using a 'minimal' version of Ubuntu 12.10 (with openbox and lightdm), installed on LVM on top of luks.
The command I use to suspend is:
dbus-send --system --print-reply --dest=
I have attached /var/log/

dmesg | grep PM for a successful (sixty second wait) suspend. Something weird is going on here:
...
[36838.168016] PM: suspend of drv:pci dev:0000:00:0f.0 complete after 1607.208 msecs
[36897.413057] PM: suspend of drv:sd dev:0:0:0:0 complete after 60860.420 msecs
...
but I don't know what that means.
