I also have this bug on MX4 with OTA13. However, I must notice that I2C_ACKERR errors also present in "good" case for me during the taking of photo. The difference between good and bad cases are that these errors appear in large quantity after the photo is taken.
I also would like to point out copious errors "inv_mpu: error in header parsing=8d00" (which could be seen in the original syslog for this bug), which also happen for me. They appear as a nearly endless spam in log when I try to focus camera on something, it seems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1537774 Title: Viewfinder frozen and all buttons disabled after taking HDR picture To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1537774/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
