Re: New device tree kernel is in testing

Ah, sorry, I thought you meant the people who aren't as smug as you. Them too (although maybe not so much smug, as incredulous). ;) This presupposes that everyone has the time, resources and expertise to test something. Warning that "this branch will become master" is not the same as warning this "...

Re: New device tree kernel is in testing

Try 90% of the overclock. It does sound like your overclock may have been borderline and the newer kernel just tickles the core in the wrong way (e.g. has a code path that rapidly goes from very low power consumption to high power consumption). OK, will see how long it stays up when the arm_freq is...

Re: New device tree kernel is in testing

Just to be sure can you disable overclock and confirm it still fails. With overclock disabled, it's now been up 4.5 days without any problem. I'd be surprised if power is a problem, as this Pi has been 100% reliable with previous kernels, runs headless, and it's not doing much when it crashes which...

Re: Hardkernel ODROID-C1 is a $35 Development Board

As I understand it, the bigLITTLE chips can only run either Big or little at the same time. It's an architecture designed for power optimisation - run the big cores when you need the power, and the little ones when you need power saving. It's actually quite difficult to write the scheduler to take ...

Does your time machine run on the Pi? Where can I get one? 24 hours notice of a lock-up is plenty to enable a pre-emptive reboot :D :shock: :o
Doh... not sure what I was thinking of there... 12 Dec 09:55! Will correct original post :)

Re: New device tree kernel is in testing

Obviously a reproducable test case would be useful. Does this affect both 3.17 and 3.18 versions? I'd be interested if the latest DT kernel with DT disabled (device_tree="" added to config.txt) is good or bad. I wish I knew how to reproduce, it seems to take 2-3 days for the lockup to occur and hap...

Re: New device tree kernel is in testing

Since switching to the device tree enabled kernel (3.17.4, then 3.18), I've experienced three hard lock ups requiring a power cycle to restart Raspbian. With the old 3.12.y kernel I would run for months without a problem. I've also had OpenELEC lockup once since enabling device tree (I can't remembe...

Is /proc/device-tree present? If so, then all is well. It should now be safe to remove any modules from the blacklist. Please let me know if you find there are still some problematic modules being loaded. Yes, with my regular config.txt I see /proc/device-tree, and I've also got "No ATAGs?" in dmes...

Adding "device_tree=" has allowed 3.17.4 to boot successfully and everything appears normal, many thanks.

Or do you want to know how fast the device could be overclocked? As per dom: I'd be intested if overclockers can post their ring oscillator value (at 1.2V), and the highest stable overclock settings, and we'll see what the pattern is. How else will you determine if there is any correlation between ...
