Disregard this link. It is written by someone who hasn't the faintest idea what they're talking about.
I can see that side of the argument, however the "fix" or "explantion" seems to be power supplies and cables - but I have all the official equipment (power supplies and USB hubs/cables). Should I really have to start experimenting with power supplies and specialised usb cables just to get it to work in a satisfactory manner?Just because you're having trouble with them doesn't mean that they're not usable. I'm sorry that you're struggling with your Pi2Bs, but mine has been running as a desktop PC and media centre pretty much 24/7 for several weeks now with all 4 USB ports occupied (WiFi dongle, wireless keyboard and mouse dongle/USB printer/external HDD) whilst being heavily overclocked and hasn't missed a beat except when I've been experimenting with pushing the limits of the overclock, which is clearly my own fault.
As a moderator said earlier, if the problems you were experiencing were common then this forum would be awash with complaints about it, but it isn't. Please stay calm and try to work through this problem logically as something is clearly going wrong at your end that isn't happening to nearly any other user.
Thanks for the reply:

It seems that the symptom is "unspecified USB/network outages". Is the Pi crashing? Is the USB bus going away? Is Ethernet just dropping out?
What is the determinant for deciding that the Pi has entered a "bad" state?
What exactly are these "cpu messages" ?The usb and network locks up (no ssh access), lots of cpu messages on the screen and only a hard reset will bring it back to life.
Right OK -Heater wrote:As far as I can tell you still have not told us exactly what you are doing. Hardware, software, the works.
Sorry if I have missed that in this thread.
Bottom line is 8 million odd Pi have been sold and as far as I can tell few have come back as "not fit for purpose". So it would be interesting to know what your special case is.

People are talking about power issues because you are talking about it being a hardware issue. *If* it is a hardware issue, the problem can most often be traced back to power problems. That reality certainly doesn't have to apply in your case.Nemo1966 wrote:Actually when I think about it the ONLY thing it crashes on is the Pi2

The vast majority of issues reported here can be traced back to power issues. So that is always the first point of call. No-one is saying that is the problem here, just that it might be the problem here. Subsequent posts seem to indicate it not power, so more investigation required. Simple as that. Try to get answers to the questions above, that will give us a much better idea of where the problem is.Nemo1966 wrote: Despite what it sounds like I like the Pi2 I am just a bit irked that it is unreliable (for me) and the answer seems to be power supplies etc when I am using official Pi equipment.

A PSU may be designed and built to output what it says on the label - but that does not mean that a few sub-standard devices will not get through testing
There may be some degradation over time as well - and if you have power hungry devices hanging off your Pi that can cause problems too...
...and then there are USB leads of very varying quality
OK. Now I understand. If I had to listen to ABBA in a loop I would commit suicide ASAP...playing the ABBA Gold album in a loop.

The Raspberry branded power supply does not use a USB-A to microUSB, the cable is fully integrated.jamesh wrote: Also, I do not know if these 'official' devices have built in USB leads or people are using any old thing. the lead is an important part and should be decent quality.
Nothing wrong with Agnetha, Benny, Bjorn and Anni-Frid they are some of the most successful musicians and singers in history.Nemo1966 wrote:haha!

But hey! it's Abba
My other half saw Abba live.Heater wrote:Certainly Abba were great musicians and massively popular. Popularity dose not ensure I will like their music or even not find it really annoying.
Back in the day I might have been happy to just ignore them as just part of the endless torrent of trivial pop music. But maybe they were too good. They created a string of catchy tunes that get stuck in your mind and play around and around, which might be nice if you like the tunes, other wise its annoying.
To compound that they are massively popular, which means we end up hearing the same old songs over and over. On the radio, in the pubs, bars and restaurants, in elevators...arrghhh make it stop!
Oddly, I don't know anyone who ever bought an ABBA record. Back in the day of buying vinyl I knew people with huge collections. I started to wonder how ABBA made so much money when nobody buys their records. Or did those people hide their ABBA disks when friends visited for fear of embarrassment
They're both based on Debian. Wheezy is the 'old stable' release, Jessie the current stable (https://www.debian.org/releases/).Nemo1966 wrote:If Jessie is an upgrade, then why even produce Wheezy? Are they based on different Linux distros?
Just crank out a track or two of Abacab to clear your head, sure it's a sell out from the days of Selling England By The Pound and The Lamb Lies Down on Broadway but at least it doesn't include, "You can dance, you can jive, having the time of your life. See that girl, watch that scene, digging the Dancing Queen."Heater wrote:To compound that they are massively popular, which means we end up hearing the same old songs over and over.
