I've been having issues with my Helios4 becoming unresponsive when it's been up for a while. I decided to do some more thorough investigating and found that it was having problems writing to the sdcard. That led to the following entries in syslog: Dec 20 21:36:43 helios-backup kernel: [318645.034243] mmc0: Timeout waiting for hardware interrupt.

I haven't yet tried using different sdcards, but that would be my next step. Has anyone else seen this?
