A small poll on the official Playstation forums is pointing to the possibility that there are potentially some serious issues with firmware v3.15. Over 50 percent of those who took part in the poll revealed that they had bad issues or a complete system failure due to the 3.15 update.
<blockquote>While it's a bit early to call things widespread, some forums are once again starting to heat up with reports of various problems that mostly seem to have occurred after the 3.15 update rolled out last month -- although some folks also seem to have had trouble with the earlier 3.10 update. As with last time, the issues being reported vary a bit, but the 60GB PS3 seems like it may be the most affected, with one completely unscientific poll on the official PlayStation forums finding that 27 users of the 60GB model had no issues after the 3.15 update, while 35 users had either some "bad" issues or a complete system failure ('course those with no problems aren't that likely to be seeking out threads about problems). So, anyone notice that their PS3 isn't behaving like it should? Let us know in comments.</blockquote>
