log from Xorg initialization
Machine: Apple MacBook Pro Retina 10.1
OS: Linux 4.5.1-1-ARCH #1 SMP PREEMPT x86_64 GNU/Linux
Graphics: Intel Corporation 3rd Gen Core processor Graphics Controller
[8086:0166] (rev 09)
Xorg Server: 1.18.3
Xorg Intel Driver: 2.99.917 (commit f2a4645)
Xorg randomly and permanently hangs in Intel driver using SNA on my machine,
with main thread eating up 100% of one CPU core. Couple of semi-random manual
breaks in a debugger show the driver spending all of this time in
sna_wait_vblank()
function.
Mouse cursor also freezes if that matters - I saw people posting this in their
bug reports.
I'm attaching:
- backtrace from GDB
- log from Xorg initialization (rest of the log was from libinput, so I cut it
out)</pre>
