Patrik, I just checked and I can see (and download) the attachment[1] even when I'm not logged in.  Can you check again?

And it seems that we still have some bad code (causing the OOPS) in the recovery flows... :(

dmesg crash and restart

A new type of crash where it managed to recover.

But I couldn't make a dump of this.
I've added the udev rule.
I expect these crashes to auto-dump, but I ran the first command and got:

[ 5945.073512] iwlwifi 0000:3c:00.0: Collecting data: trigger 1 fired.

But I don't have /sys/devices/virtual/devcoredump so I suspect this kernel doesn't have CONFIG_ALLOW_DEV_COREDUMP even though the config says so?
In that case I'll have to wait until 4-13.rc2 comes out and hopefully has the patch I'm running.
Comment 14 Emmanuel Grumbach 2017-07-20 21:04:39 UTC
You don't to do any command to create the dump. They should be created automatically when the firmware crashes.
Comment 15 Patrik Kullman 2017-07-20 21:23:09 UTC
But where? /sys/devices/virtual/devcoredump according to the wiki but it doesn't exist.
Comment 16 Emmanuel Grumbach 2017-07-20 21:29:28 UTC
It will stay there for a few minutes until some user space agent (udev rule or manual operation) collects. After a few minutes, it will be released by the kernel.
Comment 17 Patrik Kullman 2017-07-20 21:42:29 UTC
Yes well it doesn't exist so the udev rule or me can't collect it.

This intel-microcode update seems to have made a difference, the driver doesn't crash as hard anymore.

I won't be able to do much without a firmware dump.

(In reply to Emmanuel Grumbach from comment #20)
> I won't be able to do much without a firmware dump.

Please try to create a dump manually with the fw_dbg_collect command.
Then check what you have in the devcoredump directory.

thanks.
Comment 22 Patrik Kullman 2017-07-21 16:22:16 UTC
I don't have a devcoredump directory before or after running the command.

Going to see if I can have the kernel rebuilt, it probably lacks the feature.
Comment 23 Patrik Kullman 2017-07-21 19:04:26 UTC
Kernel has the feature, not sure why the devcoredump directory is missing.
Comment 24 Patrik Kullman 2017-07-21 19:10:57 UTC
I have /sys/class/devcoredump with the file "disabled" in it and the value 0.

hard crash after microcode update

So the microcode update actually didn't lessen the crash, experienced two harder crashes after.

Not sure how to proceed since the kernel has devcoredump support but the relevant directories and files are not present.

Anything else to check?
Comment 26 Emmanuel Grumbach 2017-07-24 20:38:56 UTC
The Oops is something that we can analyse and fix.

I don't have any issues with the devcoredump and everything seems to be configured properly on your end.

You can try to check what udev says while you trigger a dump (with fw_dbg_collect) with:

udevadm monitor.

I'll let Luca handle the Oops part, open an internal bug etc...
Comment 27 Patrik Kullman 2017-07-24 21:07:10 UTC
udevadm monitor:

KERNEL[3637.969539] add      /devices/virtual/devcoredump/devcd1 (devcoredump)
KERNEL[3637.976602] remove   /devices/virtual/devcoredump/devcd1 (devcoredump)
UDEV  [3637.980325] add      /devices/virtual/devcoredump/devcd1 (devcoredump)
UDEV  [3637.980738] remove   /devices/virtual/devcoredump/devcd1 (devcoredump)

So the kernel removes the dump before udev gets to handle it?
Comment 28 Emmanuel Grumbach 2017-07-24 21:15:12 UTC
Have you installed the udev rule?

Do you see anything under /var/log/ that looks like a firmware dump?

Btw, please send the iwlwifi.ko that you work with for the Oops analysis.
Comment 29 Patrik Kullman 2017-07-24 21:30:20 UTC
Created attachment 257695 [details]
iwlwifi.ko

Yes, udev rule is in place but nothing is being created in /var/log

Ubuntu seems to be using "apport" to intercept crashes and put in /var/crash but nothing there either.

Been trying to enable the functionality somehow but no success so far..
Comment 30 Patrik Kullman 2017-08-04 11:05:14 UTC
Haven't been able to produce a device coredump yet, but has also not yet experienced this on 4.13-rc3.

Comment 32 Luca Coelho 2017-09-01 19:36:12 UTC
Any luck with the dump?
Comment 33 Jeremy Murphy 2017-09-02 16:22:35 UTC
I'm experiencing much the same symptoms but with an older model, the Ultimate-N 6300. Should I join this bug or open a new one specifically for that model?
Here is the tail end of dmesg, with the symptomatic output:

Comment 34 Luca Coelho 2017-09-02 17:22:17 UTC
Jeremy, even though it may look the same at first sight, the issue you are experiencing is different.

Looking at all the A5A5A5... values you are getting, this looks like an issue with the PCIe bus.  We can't contact the device anymore.

If you want to continue investigating this, please file a separate bug.  But unfortunately I really don't think there is anything we can do about it at this stage...
Comment 35 Jeremy Murphy 2017-09-03 06:54:39 UTC
Thanks, Luca.
Comment 36 Luca Coelho 2017-09-14 07:40:54 UTC
Patrik, is this still happening for you? Did you manage to get the FW dump?
Comment 37 Patrik Kullman 2017-09-15 06:16:21 UTC
It is happening *a lot* less, but it still has happened with newer kernels.

No luck on the FW dump.
Comment 38 Emmanuel Grumbach 2017-09-17 20:36:58 UTC
