<pre>Dear all,
since 4.4-rc series I am again seeing this kind of corruption, especially after
return from sleep (suspend to ram).
This happens on a Sony VAIO Pro,
00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated
Graphics Controller (rev 09) (prog-if 00 [VGA controller])
Subsystem: Sony Corporation Device 90b6
Flags: bus master, fast devsel, latency 0, IRQ 40
Memory at f5c00000 (64-bit, non-prefetchable) [size=4M]
Memory at e0000000 (64-bit, prefetchable) [size=256M]
I/O ports at f000 [size=64]
Expansion ROM at <unassigned> [disabled]
Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit-
Capabilities: [d0] Power Management version 2
Capabilities: [a4] PCI Advanced Features
Kernel driver in use: i915
Switching to 4.3 resolves the issue.
Software is Debian/sid uptodate, that is xorg 7.7, driver-intel 2.99.917
Is this a known problem on the new kernels?
Thanks
Norbert</pre>
