for the record, I have been having the same problem multiple times, after flash and reflash when I was only web surfing and rss reading for a week. There is one time, that the system start continuous rebooting right after I update the rss feed. Well, after I have set it to dualboot, and built my own kernel and boot it off the 8GB SDHC card, I haven't had problem yet. Granted it was only about 3-4 days, but heck I haven't had that problem yet. This may be too early to call it, but it seem that rss data may have somewhat incompatible w/ the jffs2 compression algorithm, or there could be a bug in the jffs2.
