Today I experienced a series of bizarre full system freezes when editing in Premiere Pro CS6 (version 6.0.1). I was editing in a 1080p 23.967 sequence and had just added some keyframes to still images, and when I attempted to place the playback bar to preview the keyframing, my Mac completely froze immediately. Everything froze, not just Premiere Pro. Mouse cursor was the only thing under my control. I was forced to do a hard reboot.
Second attempt: I attempted to redo the image keyframing, since I didn't have a chance to save (nor have PPro auto-save). I did the exact same procedure and the system froze like before.
Third attempt: Thinking that for whatever reason, PPro didn't like this .jpg image, I saved it as a .PSD and reimported it into PPro. I was finally able to keyframe it, but then I attempted to playpack some clips in the timeline ahead of the images and the system froze again.
I restarted again, and luckily had saved my work after keyframing, and I went about the rest of my editing of my project. I avoided playback of the sequence near the parts with the still images. Everything was fine, and the video exported properly and looked great.
Between crashes I was able to sneak a glance at the Console, but unfortunately there are no crash reports to share. I was able to scroll back through the console messages and I saw a bunch of entries:
kernel[0]: ** GPU Debug Info Start **
kernel[0]: 0x0000944a
kernel[0]: 0x000000cb
kernel[0]: 0x00000001
kernel[0]: 0x00000018
kernel[0]: 0x0000d062
kernel[0]: 0x00000001
...
I had tons of these kernel entries repeated multiple of times right before the Console entrie for the system reboot message. From my uneducated guess at Console error, I'm guessing it has something do to with the GPU.
My system is an Early 2011 17" MacBook Pro 2.2Ghz Core i7, 16GB RAM, 480GB OWC SSD, AMD Radeon 6750M 1GB gpu. I'm running 10.8 and all my Premiere Pro media is being stored on FW800 drives.
Any ideas?
Thanks,
William
