<pre>I'd like to start with noting this issue has been occurring for years on most
of our iMacs and I strongly suspect this isn't necessarily "caused" by nouveau
but rather by an implementation detail NVidia forgot to document (please remind
me why I keep buying their hardware?)
Hardware: Apple Inc. iMac13,2/Mac-FC02E91DDD3FA6A4, BIOS
IM131.88Z.010A.B05.1211151146 11/15/2012
Software: Archlinux / any nouveau release, currenty running xf86-video-nouveau
1.0.16-1
Using Xorg this iMac hangs maybe 2 or 3 times a day, using Xwayland (using
sway, a native wayland implementation) there actually is a backtrace and I have
a chance to reboot instead of kill the power. I'd love to help debug this since
I assume it only happens when using this specific hardware. To start with -
here is a backtrace:
