Hey guys,

i know, there are a lot of threads talking about high load, but mine problem is only when the screensaver (black) is active... well it could be that it is after a while and not because of the screensaver.

I have a dualcore AMD E-350 with 2 gb ram, 1 x 320 gb HDD, 1 x 2 TB HDD running xbmcbuntu upgraded to 13.04, removed pulseaudio. I have a samba and ftp server running too on the same machine, but i think those servers have nothing to do with my problem.

At this machine i have connected a wifi keyboard, my plasma-television and my hifi-stereo. To use the XBMC i use my smartphone to navigate or to start whatever i want to watch or listen... BUT... after a couple of minutes the screensaver puts the screen in black and my cpu is running on one core at 100 %

Here is my xbmc.log
http://paste.ubuntu.com/5911351/

when i start strace i see only those lines:

Code:
ioctl(19, 0xc00c645c, 0xbfa169b0)       = 0
ioctl(19, 0xc00c645c, 0xbfa169b0)       = 0
ioctl(19, 0xc00c645c, 0xbfa169b0)       = 0
ioctl(19, 0xc00c645c, 0xbfa169b0)       = 0
ioctl(19, 0xc00c645c, 0xbfa169b0)       = 0
ioctl(19, 0xc00c645c, 0xbfa169b0)       = 0
ioctl(19, 0xc00c645c, 0xbfa169b0)       = 0
ioctl(19, 0xc00c645c, 0xbfa169b0)       = 0

and this stops only when i press a key on the keyboard or i press the cursorbuttons on the smartphone.

When i start a movie or something my smartphone keeps waiting on any response, but nothing happens, and after 5-8 seconds the smartphone looses the connection to the xbmc

so i waited looking in the strace before that happen, but i don't have any idea what is the problem now.

wsnipex xvba version !


When i press any key on the keyboard, the screensaver stops and the system is on a normal load... maybe 6-9% cpu load (for me very good)

I hope someone can help me. If i forgot something tell me what you need and i will post it!

13.04 has by default 100% CPU Load on you amd hardware ... driver bug. The Upgrade was a real bad idea.

well, i installed xbmcbuntu yesterday from the scratch and i upgraded like i have had it before......... i can't believe that. thanks man

do you have a link to bugzilla or something, i don't know what to search for. what is the reason for that problem?

fritsch

2013-07-25, 21:21
Reason: Bug in every catalyst driver > Catalyst 12.10. It was fixed in 13.6 beta which introduced other bugs ...

Okay, thx... i tried to disable vertical blank synchronization and for now it helps. cpu usage is at 4% within the last 15 minutes Smile

Yes, exactly this is the bug :-( Happy watching movies without vblank sync.
