Hi,
on Monday I did an system update (pacman -Syu) which updated among others the following packages:
$this->bbcode_second_pass_code('', '
raspberrypi-firmware-20130721-1 raspberrypi-firmware-bootloader-20130721-1 raspberrypi-firmware-bootloader-x-20130721-1 raspberrypi-firmware-emergency-kernel-20130721-1 raspberrypi-firmware-examples-20130721-1 raspberrypi-firmware-tools-20130721-1
')
After an immediate reboot my raspberry didn't come up i.e. no boot screen just the red light on. So I tried several things like downgrading the firmware packages to *20130707* and the things suggested on: http://elinux.org/R-Pi_Troubleshooting Nothing helped. So I simply copied the boot partition of the original image to my sdcard which did work and still works. Curious as I'am I did a pacman -Syu again which updated the packages above (because of the downgrade), I rebooted immediately: again only the red light.
For now I again just copied the original boot partition to my sdcard which works. But I'm afraid with the next update my raspberry crashes again.
So without a clue whats going wrong I'm asking you guys for help.
