Comment (by danielk):

 Hmmm, this is very strange, it seems to be spending all it's time
 rescheduling, not
 in writing to disk.

 Can you try disabling EIT parsing? To see if that makes the problem go
 away.

 Also when you rerun OProfile try this
 {{{
 opcontrol --image=/usr/local/bin/mythbackend -e
 CPU_CLK_UNHALTED:10000:0x00:1:1 /etc/init.d/mythbackend restart
 }}}
 It lowers the cycles between samples from 100,000 to 10,000 which should
 give you more meaningful results more quickly. If opcontrol doesn't allow
 such a low value, it should tell you what the minimum is.
