Laptop crash: kernel NULL pointer dereference

My laptop sometimes become completely unresponsive, and I have to force restart it. `journalctl -b -1` shows (last lines of log):

Re: Laptop crash: kernel NULL pointer dereference

My system generates the very same error. I have a hostapd based wifi AP setup with a NAT between intel 7265D and Realtek ethernet card. I have noticed that after powering any of my laptop devices or an iphone, they try to (re)connect with this hostapd wifi AP of mine automatically and it is what often triggers this kernel error in my hostapd ap/router setup. I somehow don't observe the same trigger happen when my Android phone tries (re)connecting to my wifi AP setup. I hope this helps to further investigate your issue.

Re: Laptop crash: kernel NULL pointer dereference

I have just started having similar issues also in my desktop with an Intel wifi card. It doesn't completely lock up though, I am still able run some things and issue a "reboot" command, although I get a number of errors during shutdown, EDIT: and it doesn't seem to ever finish, requires SysRq reboot or hard reset.

I recently changed some settings in my router (basically fixed channel and bandwidth, and split 2.4Ghz and 5Ghz to separate SSID) and I didn't see this issue before, not sure it is related though. Router changes was done due to a laptop having problems with ath10k firmware crashes (similar to this) and so far I have not have any issues with this, (running about a week or so).

I haven't had time to test different combinations though, but I'll try some other router settings later on to see how it affects stability.

EDIT: adding journalctl entry for reference:

Re: Laptop crash: kernel NULL pointer dereference

Thanks for those two bug links, which played a very central role in my further digs. The very same bug of OP was also reported to Arch Linux about a month ago appearently, and its reply said something about a fix arriving after the Kernel 5.3 updates only. ( For reference: https://bugs.archlinux.org/task/63185 ) It means that there might be many months before a fix is offered in kernel updates even if the diagnosis are correct in that bug report. Therefore, I am interested in identifting some sort of a config setting to make comprimises in the available features set of my wifi card or network connection, battery management etc. Can anyone take a look at the log file of OP and come up with some hostapd.config or iwlwifi.config pareter to disable the problematic feature for letting the AP setup still run at subpar performance rather than a crash?

Re: Laptop crash: kernel NULL pointer dereference

tarkan you could try linux-mainline from AUR which is currently at linux 5.3-rc4 which contains the commits mentioned in 63185 plus updates for iwlwifi.

Re: Laptop crash: kernel NULL pointer dereference

I am experiencing the same crash a similar crash with: 5.2.8-arch1-1-ARCH (maybe time for a new topic)
I was able to sync and reboot with sysrq.
Here it seems to be the amdgpu driver having issues:

I am now on linux-lts 4.19.66-1-lts which seems to run fine. I will test 5.3-rc4 when I get the time but I doubt it will help for amdgpu problems.

Re: Laptop crash: kernel NULL pointer dereference

@JoeCool possibly https://bbs.archlinux.org/viewtopic.php?id=247761 NULL pointer dereference is a class of error.

Re: Laptop crash: kernel NULL pointer dereference

Thanks, @loqs.That looks like a similar error. Yeah I noticed too late this topic is about the iwlwifi driver. Sorry.

Re: Laptop crash: kernel NULL pointer dereference

I have been running the last day and a half on only 5Ghz (after splitting two different SSID for 2.4Ghz & 5Ghz) without problems, which I see as a good sign. But difficult to say what is the determining factor though (frequency change, avoiding auto-switching, reducing other clients on same SSID etc.)

My system generates the very same error. I have a hostapd based wifi AP setup with a NAT between intel 7265D and Realtek ethernet card. I have noticed that after powering any of my laptop devices or an iphone, they try to (re)connect with this hostapd wifi AP of mine automatically and it is what often triggers this kernel error in my hostapd ap/router setup. I somehow don't observe the same trigger happen when my Android phone tries (re)connecting to my wifi AP setup. I hope this helps to further investigate your issue.

...might just be something as you suggest. I currently have this computer (with intel 9260) and an Android phone on this 5Ghz SSID/network. Previously iPhone + other laptop was on the same.

Re: Laptop crash: kernel NULL pointer dereference

@loqs; Thanks for the suggestion. I have built my 5.3-rc4 yesterday and gave a test run for 24 hours under the same AP setup conditions. I am here to report that I received the very same Kernel error only once so far, which would be more than 3-4 errors otherwise based on how I tested in both Kernel cases. What surely triggers this error in 5.2, seems to only randomly trigger in 5.3 version. Although this error generation rate might seem like a major improvement, the underlying problem apparently doesn't get fixed yet with 5.3 version either.

@skylla; Thanks for the 5Ghz tip. Since Intel cards don't allow AP mode in 5Ghz frequencies, I am unfortunately unable to confirm anything in relationship to the different frequency choices under the Kernel 5.3-rc4 version.

I investigated and found kernel-mainline a bit too bleeding-edge for my use purposes in my setup. I think setting up a production server in a rolling release based linux distro is daring enough by itself to me, so I probably shouldn't aim at becoming a hero now. I am once again favoring a config based temporary fix to this error if possible. I would like to stay with the default kernels of Arch Linux since this box serves not only hostapd, but also nginx, mysql, php, smtp, dns, coturn, redis etc. It is a busy busy box...

Could anyone identify some sort of a configuration setting to make compromises in the available features set of my wifi card drivers, battery management settings, or network connection parameters etc. Thank in advance.
