Re: [beagleboard] Debian 8.1 / kernel 4.1.x test releases are unstable
What does cpufreq-set -g performance do? Sounds like it would lock the BBB at max CPU clock speed, or at least, not let it go down to the lowest speeds. I found the generic Debian docs on *cpufreq-set*, but not the BBB specific instruction set and meanings. --- Graham On Mon, Jul 13, 2015 at 8:41 AM, Graham Haddock gra...@flexradio.com wrote: OK.

No other changes. Then I went to bed. Reading syslog, (Times are GMT, boot completion defined as systemd updating the time to network time. the initial boot (completion) was at JUL 12, 05:09:27 the lab was quiet, lights off, nothing running.

So, I'll work on the problem bottom to top. What I mean by this is that I'll start with a rootfs I know that works. In my case wheezy 7.8. I've got that running now with debian@beaglebone:~$ uname -a Linux beaglebone 4.1.0-rc8-bone9 #1 Tue Jun 16 23:45:22 UTC 2015 armv7l GNU/Linux. I'll let it sit and idle for a day or so. After that, I'll download and flash the Jessie image, install sysv, disable systemd. Then start the test over again. Oh and yeah if one of you can do me a favor and run one of your boards as is with *sudo cpufreq-set -g performance* and see if the problem clears up ?

Re: [beagleboard] Debian 8.1 / kernel 4.1.x test releases are unstable
Thanks Peter for the in depth explanation.

Currently I'm in the process of reading / learning advanced Linux programming, and have all these crazy ideas of what we could do. Just not sure what to trap and exactly 100% how to trap it. Linux mainline kernel source is really just a massive linear series of patches, one after the other, all tracked by git. Bisecting is a method of reducing the number of patches under test by 1/2 at each iteration to arrive at a problem commit. So, for example, let's say that I have a problem that cropped up on 4.2-rc1, but the problem wasn't happening on 4.1-rc7. I start a bisect with git: $ git bisect start v4.2-rc1 v4.1-rc7 Bisecting: 6261 revisions left to test after this (roughly 13 steps) [4570a37169d4b44d316f40b2ccc681dc93fedc7b] Merge tag 'sound-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound I build this kernel, test it, and mark it good or bad. Let's say the problem doesn't exhibit in this kernel. $ git bisect good Bisecting: 3371 revisions left to test after this (roughly 12 steps) [8d7804a2f03dbd34940fcb426450c730adf29dae] Merge tag 'driver-core-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Now I build this kernel, test it, and mark it good or bad. Let's say bad this time. $git bisect bad [3d9f96d850e4bbfae24dc9aee03033dd77c81596] Merge tag 'armsoc-dt' of git:// git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Each time, the number of commits under test are being reduced by 1/2. For a small kernel like Beaglebone this is no big deal, couple of minutes build time. For a 64-bit distro kernel, this can take several days for 14 iterations. Having a bunch of BBBs, all testing the same kernel at the same time significantly improves the confidence at each iteration that the kernel is good or bad (since obviously a problem that takes time to manifest may be mistakenly identified as good and then the bisect will narrow on the wrong commits). Instrumenting a problem like this is basically impossible.

[beagleboard] Debian 8.1 / kernel 4.1.x test releases are unstable
I have several Rev C BBB units, that have been in use enough to be considered trusted hardware. All of them, running Debian 8.1 kernel 3.14 are rock solid. By that, I mean that they will run for months without problems. Maybe longer, I have not left them undisturbed for any longer than that. I have tried to run the Debian 8.1 / kernel 4.1.x test releases, and they all autonomously reboot several times per day. No regular or reproducible pattern, nothing in the syslog, other than the reboot process itself. This includes the 2015-07-05 kernel 4.1.1 release. (bone-debian-8.1-lxqt-4gb-armhf-2015-07-05-4gb.img) All I do is put it on a 16 GB card, expand the available memory to 16 GB from 4 GB, and turn off the 4 blinky lights. No other changes. The unit will reboot at random, several times per day. This has been common to all the kerenl 4.1 releases. Although a random pattern to the reboots, it is easy enough to reproduce. If you turn off the blinky lights, it is easy to recognize, since they come back on when it reboots. Or examine the syslog. --- Graham == -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

By that, I mean that they will run for months without problems. Maybe longer, I have not left them undisturbed for any longer than that. I have tried to run the Debian 8.1 / kernel 4.1.x test releases, and they all autonomously reboot several times per day. No regular or reproducible pattern, nothing in the syslog, other than the reboot process itself. This includes the 2015-07-05 kernel 4.1.1 release. (bone-debian-8.1-lxqt-4gb-armhf-2015-07-05-4gb.img) All I do is put it on a 16 GB card, expand the available memory to 16 GB from 4 GB, and turn off the 4 blinky lights. No other changes. The unit will reboot at random, several times per day. This has been common to all the kerenl 4.1 releases. Although a random pattern to the reboots, it is easy enough to reproduce. If you turn off the blinky lights, it is easy to recognize, since they come back on when it reboots. Or examine the syslog. The common debugging method for problems like this is to bisect. However, if the start and end points are 3.14 and 4.1.x, respectively, that would be prohibitive. Best to find a closer start point than 3.14. Also, is 4.1.x stable if you don't mess with the image?

I will try it by reloading a totally untouched bone-debian-8.1-lxqt-4gb-armhf-2015-07-05-4gb.img, and report back. No cape, trusted Rev.C hardware and power supply. All communications via Ethernet. By my saying that 3.14 is rock solid, this includes up to bone-debian-8.1-lxqt-4gb-armhf-2015-06-15-4gb.img, which was the last non-kernel-4 test release. Same hardware, same power supplies, same Ethernet connection. No other hardware or connections. --- Graham == -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

If I look on one - but not the target worst case Beaglebone, I see only one package matching Robert's suggestion apt-cache search linux-image | grep ti | grep 4.1 linux-image-4.1.1-ti-r2 - Linux kernel, version 4.1.1-ti-r2 However, if I want to apt-get update on the two current worst case targets, I am getting Get:10 http://ftp.us.debian.org jessie-updates/non-free armhf Packages [20 B] Fetched 9247 kB in 20s (457 kB/s) W: Failed to fetch http://repos.rcn-ee.com/debian/dists/jessie/main/binary-armhf/Packages Hash Sum mismatch E: Some index files failed to download.
