I think it might be a Raspbian and few other distros problem. the corruption issue is out of control. I understand when it happens if there is a power failure that results in a reset. but I don't understand why it happens when there is a normal shutdown/reboot. just before a while, I had corruption and this one not in my sd card, but in the hdd. (I moved root and most of the filesystem to hdd thinking it might be sd card thing) I did fsck from linux on pc and there were lots of errors.
causes I've read including voltage, which makes sense, but should this happen with normal booting cycle?
things to know , I do have issue with power adapters, please see this thread for more info: http://www.raspberrypi.org/phpBB3/viewtopic.php?t=53093
but I thought things started to work normal, when the dreaded kbd of death suddenly happened after a normal reboot.
Might be helpful info, in case someone with similar experience:
my overclock config:
Just before this last corruption, I installed omxplayer, yt (youtube) and xmbc (without boot and mount options)
I have emulationstation set to start instead of x.
other corruption cases, mostly related to sudden reset. except one time right after trying to play a youtube video in browser, started giving segmentation fault and sd card corrupted (before I resort to hdd solution) . this time I also tried to do the same thing (coincidence?)
