Canon EOS 5D Mark II 2.0.3 firmware yanked due to audio issues, fix is on the way

It's not déjà vu, it's just all happening again. Just over a year after Canon had to bow its head in shame due to a black dot / banding issue that plagued the EOS 5D Mark II, along comes yet another heartache surrounding one of the company's finest DSLRs. The v2.0.3 firmware update that was issued earlier in the week is apparently causing audio problems for some users, with the actual quirk going a little something like this:

"Recently we have discovered a malfunction that occurs with Firmware Version 2.0.3, in which the manual recording levels for C1/C2/C3 are changed and the camera becomes unable to record audio if the power is turned off (or if Auto power off takes effect) after registering "Sound Recording: Manual" in the camera user settings. We apologize very sincerely for the inconvenience, but we are going to stop making this firmware available for download. For customers who have already updated to the new firmware, when using the camera with the mode dial set to C1/C2/C3, please either set the sound recording settings to Auto."

In the meanwhile, Canon has pulled the update from its support site while it works on a new firmware version to patch things up, but aside from a promise of "soon," there's no way to tell when exactly the new file will hit the pipes.
