Hi Christopher, I was having the issue as late as two days ago and I have upgraded to the latest kernel: uname -a Linux xbmcbuntu 3.5.0-999-generic #201207240436 SMP Tue Jul 24 08:43:51 UTC 2012 i686 i686 i386 GNU/Linux
As the issue is intermittent, I shall monitor it over the next 4 weeks (it can happen many times a day or as little as once a month!). Cheers Douglas. Quoting "Christopher M.
