I use Ubuntu 13.10 x64. I run XBMC Alpha Git 10 using HDMI output.
I use Ubuntu kernels from mainline
(http://kernel.ubuntu.com/~kernel-ppa/mainline)
Kernel 3.8.x / 3.11.10 (and some others kernels) work fine and every
frame is rendered properly.
Problem:
Using kernel 3.12.1 / 3.12.7 (I tested only these two) video playback
skips several frames per second.
Mainboard: Intel DH61AG
BIOS: AGH6110H.86A.0106.2013.0509.1441
CPU: Intel i3-3240
Memory: 4 Gb
One SSD is being used
I am attaching logs from dmesg - there are visible differences between
3.11 and 3.12, e.g.
ACPI: \_SB_.PCI0.TPMX: can't evaluate _ADR (0x5)
ACPI: \_SB_.PCI0.PDRC: can't evaluate _ADR (0x5)
ACPI: \_SB_.PCI0.DOCK: can't evaluate _ADR (0x5)
