[Openchrome-users] problem with resume after suspend to ram with epia SP8000

[druyts pascal]

I tried suspend to ram (S3) on the epia SP8000 with the openchrome driver 
(last svn version). When resuming, the graphic output is not restored 
correctly, it shows no image but only vertical color lines. Is this a bug or 
does the openchrome driver not support acpi suspend and resume?

I also tested the via driver. With that driver, suspend and resume is 
working correctly. I am using the SP8000 as a frontend for MythTV and the 
suspend/resume is very convenient. While suspended, the box remains cool and 
it takes less than one second to be up and runing again --- to be compared 
to more than 1 minute for the full boot procedure.  With Mythtv, the only 
problem is that  after a suspend/resume, it is as if the remote was plugged 
out and in again. Therfore, lircd crashes and the remote does not work 
anymore after resume. As a workaround, I restared the lircd and the frontend 
after resuming. A better workaround I am working on is to use an 'lircd 
proxy' that reads from a fifo and writes to the socket /dev/lircd. I then 
start lircd to write on /dev/lircd1 and irw /dev/lircd1 > fifo_file to feed 
the fifo with the output of the remote. Doing so, after a suspend, only 
lircd has to be restarted and mythfrontend continues to work with the 
remote. If someone is interested, I can post the lircd_proxy and the 
corresponding scripts.

Is it planned to support acpi in the openchrome driver or is it already 
supported and did I miss something?

Thank,

Pascal
