Bug Description
On my HP Elitebook G3 the wifi has not worked correctly in current or previous Ubuntu versions (18.04, 18.10).
The symptoms are that the WiFi keeps breaking the connection with no apparent reason, making the device hard to use online. There are a ton of reports regarding iwlwifi problems with the Intel 8260 chip, but nothing conclusive.
Interesting detail is that Manjaro Linux 18.0.4 seems like it would be more stable the Ubuntu.

When working via NFS, I get this every day. It may take some hours, depending on the workload, but it happened always. With simple browsing or ssh I've not encountered this. I'll try if other workloads like rsync trigger this too.

What you can try is to enable debug on iwlwifi:
debug=0xC0800000
Along with the firmware dump [1], this may help to see what happens..

I've loaded iwlwifi with debug=0xC0800000, but /sys/kernel/
However the bug depends on speed an direction. Pushing data in the LAN with rsync triggers the bug immediately, whereas pulling in LAN works perfectly. Synced more than 30GB without any problem. Syncing data via ISP works too. It only happens when pushing data with high speed.

I am not surprised. This firmware crash is about the Tx path.
If you can reproduce quickly, you can try to run with tracing.
Don't bother with debugfs for iwlwifi. Just put the udev rule in place and check that you have a dump being created when the firmware crashes. You don't need debugfs for that.

Ok, either the bisect is wrong or it's only part of the problem. Simply reverting this commit doesn't solve the problem. Tested on top of 5.1-rc7.

This can't really be the culprit. You are not using P2P Device I presume.. and even then, it wouldn't be related to the ASSERT EDC you're seeing.
I opened a ticket on the relevant team.

Sadly with this firmware the speed is so limited, I'm not able to reproduce the bug. With debug-firmware, I achieve only 2-3MB/s, without debug it's more than 40MB/s.

I"ve double-checked, and it's always the same. With debug-firmware, speed drops to 2-3MB/s.

Yes, I've not tried to figure out, what speeds are necessary for triggering this bug. With 10MB/s it didn't happen, but with 40MB/s and more the bug occurs within seconds.

I think I was wrong when I started to look at the firmware. This smells more like a driver issue now.
Is bisection something you could consider?
If not, we'll try to see on our end.

My device is an Intel Corporation Wireless 7265 (rev 59).
I can reproduce this within a few minutes of booting a VM with the disk on an NFS share. The crash only seems to happen when using NFS and the Wifi card is hitting fairly high transfer rates >10MiB/s

I can fairly consistently repro this without using NFS on a Lenovo T460s (Intel 8260 WiFi card). If I boot up my laptop on kernel 5.1.3, open a web browser and run a speed test while on WiFi, the speed slows to a crawl and when I check dmesg I see the same trace (although different addresses, not sure if that's relevant). Downgrading the kernel to 5.0.x fixes the issue for me.
Please let me know if any additional traces would be useful.

So, you're saying the patch in comment 42 by itself is sufficient to work around the issue?

I can confirm it does work around the issue on my 7265 wlan. But I believe it's not a fix, just a workaround. (it disable some functionality I guess)

Thanks.
Yes, in a sense; it does disable some functionality that in theory lets you reach a bit higher throughput, but we enabled this functionality by accident rather than intentionally on older devices and (clearly!) never tested it carefully there, so chances are we won't actually have the bandwidth to go back to the older devices and carefully analyze and understand why it breaks there.
(FWIW, we're talking about a device that was released 4 years ago and obviously was in development significantly before that)

I had actually been referring to 8265 when I said 4 years ago - 7265 is even older :-)
As you can see in the code change, we really supported/tested this only from 9000 series onwards.
I'm still sort of curious what happens, but it remains to be seen if I can find cycles to investigate further. Most likely not.

Unfortunately we're already in v5.2-rc7, so it will be difficult to still get it in for v5.2.
To gauge the importance of this, does the assert (FW crash) disrupt connectivity much or is it just a hiccup from which we recover with a FW restart?

It's a performance killer. When this happen, transmission drops from ~40MB/s down to 1MB/s.

In my case (duplicate bug 203929), it drops connectivity and doesn't recover. I'm forced to rmmod/modprobe to get connectivity back. But that only keeps it working until the next time it trips this assert.

full dmesg log
With kernels 5.1.0-rc I noticed these microcode errors when working via NFS. Testing with kernel 5.0 didn't reproduce it. I wasn't able getting a coredump as described in https:/ /wireless. wiki.kernel. org/en/ users/drivers/ iwlwifi/ debugging, cause /sys/kernel/ debug/iwlwifi does not exist on my system.
