Comment 5 Andrew Morton 2013-11-07 20:08:09 UTC

Is this repeatable or a once-off?

Created attachment 113771 [details]
I am sure that I don't have problems with RAM. Look this proof.

This collects all the disk fails, random USB fails, memory scribbles into one bug.

Comment 28 Mikhail 2013-12-19 04:30:50 UTC

Alan, did you do it for nothing. Problems with USB not relate to this. And why did you decide that it's all refer to one and the same problem? Now I sit on another machine (another mb, different chipset, different CPU, different video card, other memory) errors in dmesg is still there. This is the same really? see the attached file?

Comment 31 Alan 2013-12-19 12:47:00 UTC

You posted a collection of reports from one box showing
- random memory errors
- disks failing in ways that cannot be triggered by the OS
- USB device failures eg

[ 1579.293396] hub 1-5.1.5:1.0: 4 ports detected
[ 1579.509535] hub 1-5.1.5:1.0: hub_port_status failed (err = -71)
[ 1579.514412] hub 1-5.1.5:1.0: cannot reset port 1 (err = -71)
[ 1579.519779] hub 1-5.1.5:1.0: cannot reset port 1 (err = -71)
[ 1579.525305] hub 1-5.1.5:1.0: cannot reset port 1 (err = -71)
[ 1579.530035] hub 1-5.1.5:1.0: cannot reset port 1 (err = -71)
[ 1579.530040] hub 1-5.1.5:1.0: Cannot enable port 1.  Maybe the USB cable is bad?

which point to hardware or electrical problems - bad devices, bad cables, bad power etc.


So I've lumped them all together because it is pointless anyone looking at the various things filed about that machine except in the context of all the other failures.

Comment 32 Mikhail 2013-12-19 13:11:47 UTC

what about last dmesg? This is fully another well known hardware which works fine with old kernels two year ago.

Mikhail,

Are you saying that if you drop down to an older Kernel this problem disappears and functions normally?  Have you tested this recently if so?

Comment 34 Mikhail 2013-12-20 18:40:56 UTC

How many times I must test my memory with memtest for you believe me that my hardware is ok and begin investigate my problem?

Comment 35 Mikhail 2013-12-20 18:41:58 UTC

Memtest doesn't tell all.  If you haven't already (recently) you need to prove the older kernels still work fine.

Drop down to what you mentioned worked and see if it still works without error.

Comment 37 Alan 2013-12-20 23:55:43 UTC

1. Memtest tests memory. It won't test for example power supply overload (which is what the disk/usb reports look more like), nor cooling, nor overclocking problems, nor sitting under a radar mast, nor bios faults, nor missing microcode updates and so on

2. Bugzilla is used for tracking stuff, it's not used to decide to investigate a problem. That is between you, your distribution and whoever/whatever support arrangements you may have.


The USB one looks like a problem seen with 3.11/3.12 on some usb storage setups and already under investigation - but hard to tell with untrustable hardware.

Comment 38 Mikhail 2013-12-21 06:04:20 UTC

I was tried several power supplys and I really don't think that power supply of good brand as Thermaltake 750W will overload if I plug 1CPU, 1HDD, 1SSD. I not to use discrete video card, only integrated video in Intel CPU. Also I use very good cooling Zalman CNPS14X.

I don `t know how else to prove that my hardware is well tested and correctly. I see here messages, that kernel developers could not help me 'cause I have faulty hardware, me it is insulting to hear that.

I am developer too, but I don't know linux kernel and I want to help, I can do any experiments on my hardware and attach here log messages.

Comment 39 Alan 2013-12-21 17:03:05 UTC

There are a couple of things worth trying as initial steps

- minimising the drivers loaded
- trying to find a pattern that reliably triggers the problem

Another thing to try as a possible starting point is to build a kernel with all the power management features disabled.

Comment 40 Mikhail 2013-12-29 10:00:58 UTC

Ok, which drivers I can block with /etc/modprobe.d/blacklist ???

re-enabling...

More hardware electrical noise/power type problem reports being logged.

Comment 46 Mikhail 2013-12-30 22:37:11 UTC

Are you kidding? This is my no means the most the first computer I have collected a lot of different computers from Socket 7 to Socket 1150. I've never had such problems, always just a good power and cooling, as well as UPS, serviceability of equipment has more than 100 hours without failure memtest. I am sure that most likely to blame the video driver, as Haswell probably still not good enough have debugged. But why do you still feel that I have electrical noise in the system case? :(

Comment 47 Mikhail 2013-12-30 22:38:20 UTC

Created attachment 120311 [details]
memtest running 145 hours without hangs!!!!

Comment 48 Alan 2013-12-30 23:38:55 UTC

Because that is what the hardware is logging. Your USB hub disabled the device, which normally occurs because of electrical noise (EMI). I'm just looking at what is being logged. Nothing more.

Replaceable internal video with Geforce 8600GT have no effect.

Having some times error's similar memory problems, but memory is fine!!!

I thing PCI bus controller fault or the firmware or driver. How this can be confirmed?

Comment 50 Alan 2014-01-05 14:29:13 UTC

 { HostInt PHYRdyChg 10B8B DevExch }

is the hard drive being changed. So either a physical device change or it went offline and came back - something the OS can't really trigger and again suggestive of power problems.

Comment 51 Mikhail 2014-01-06 19:34:35 UTC

> is the hard drive being changed.
yes. defferents SSD are tested

And can said more if I add to /etc/modprobe.d/blacklist.conf
blacklist snd-ice1724 system being bootable so it can not be associated with hardware.

What again cause?

Comment 58 Mikhail 2014-02-17 12:03:44 UTC

Alan can you add any extra debug information for catch problem?

Comment 59 Alan 2014-02-17 16:21:24 UTC

Nothing I can currently see to add. It's just an apparently broken board. It could be something else but there isn't really anything to go on.

There are lots of threads on the internet about Gigabyte *87* boards being unreliable with four DIMMs loaded but not much else of use

etc

Comment 60 Mikhail 2014-02-17 18:50:30 UTC

Alan, I was having problems with memory only  when was  installed Corsair Vengeance [CMZ16GX3M2A1600C9] memory, and memtest showed that this memory have defects, and shop where I buy hardware replaced this memory by guaranty on Kingston HyperX [KHX1600C10D3B1K2/16G]. So now with Kingston HyperX [KHX1600C10D3B1K2/16G] on GA-Z87M-D3H motherboard I have pass memetest with week testing. So I do not understand why can be problems with memory if I can `t find them.

Comment 63 Mikhail 2014-02-25 02:09:24 UTC

Alan 71111 is not duplicate. Reproducing is different. In 71111 i connect via USB my old HDD device and when it begins in an attempt to read the information make sounds beep-beep this hang is happenes.

Comment 64 Stanislaw Gruszka 2014-03-01 16:30:23 UTC

(In reply to Mikhail from comment #63)
> information make sounds beep-beep this hang is happenes.

beep-beep like this  http://en.wikipedia.org/wiki/File:Buzzing_Speakers.ogg ? 

This could indicate that there is strong radio emitter nearby (i.e. radar) or electric power transmission lines that make board malfunction.

Comment 65 Mikhail 2014-03-01 18:02:04 UTC

beep-beep sound of HDD (no MB)

Comment 68 Alex Outhred 2014-03-04 02:06:20 UTC

Treating this as an umbrella bug for bitflips and power supply issues affecting Gigabyte Z87 series motherboards, I'll make a public service announcement.

This URL may be a source of beta BIOS versions (I cannot vouch for their authenticity or functionality):
http://forums.tweaktown.com/gigabyte/28441-gigabyte-latest-beta-bios.html

For some of these motherboards, a more recent BIOS may reduce or eliminate these mysterious hardware errors. You should probably also "load optimised defaults" in the BIOS settings in case some previous BIOS version has left bad state lying around.

Comment 69 Mikhail 2014-03-19 06:55:58 UTC

Problems with various memory bitflips scribbles on Gigabyte *87* boxes seems fixed with latest 3.13.6 kernel and latest BIOS F10
