Not booting after updating firmware

Hi,

I'm using DAC+, and I have a problem doing what is written here : http://www.hifiberry.com/guides/hifiberry-software-configuration/

Indeed, after updating firmware (sudo rpi-update) and reboot, the system actually doesn't boot anymore : I have that classic rainbow startup screen, and then a second one with a small red square at the top-right of the screen. It stops there.

When I remove the DAC+, it's booting fine.

Any idea?

Many thanks!

  Dear Benoit,
  
  we haven't seen this before. Maybe the power supply is not stable enough?
  Did it boot without problems with the old kernel and the DAC+ plugged onto it.

  Hi,
  
  Yes it did boot well with the old kernel and the DAC+.
  
  As a power supply I've used 2 different ones: one from a HTC cellphone, one from a Nokia one - 5V and 1A / 1.2A. Is a cellphone power supply generaly good enough?
  
  If you have no idea, I'm gonna try with a fresh OS and feed back here... I've asked this on RPi forum also.
  
  Thanks!

  Same problem after a fresh install + firmware update...

  What distribution are you using?

  I'm using Raspbian.
  I'm still trying out, but it seems that updating all software and distribution fixes the problem... It worked once, trying to reproduce.

  Hmm, interesting. This almost looks like the kernel was upgraded, but not the firmware. This should not happen with rpi-update.
  I'm very interested in your feedback. If it needs a full upgrade first (usually I dod this), we will add this to our guide.

  Unfortunately, upgrading everything only worked on a fresh install (once at least), not on a "real" one.
  The mystery remains unsolved for me, and I have no way to debug RPi's firmware errors...

  Dear Benoit,
  
  
  what is a "real" installation? How did you install your Raspbian? What other software did you install on it? This is very unusual.
  Can you test our test image from here (it is based on a very small Raspbian installation):
