Ive tested using Kernel version Kernel 4.17 rc8, Kernel 4.16.8, Kernel 4.12.8, and Kernel 4.14 across Manjaro Linux, Ubuntu Linux, Opensuse leap 15 and Fedora 28. Steps to trigger: -Open firefox with many tabs, or any other high memory usage program -Wait a second -System freezes. Sometimes the only fix is a hard reboot Other findings: -I notice really high cpu load averages if the system unfreezes -If the system is not frozen, it is highly unresponsive on high memory usage when swapping in my expierience -Hard drive indicator light stays solidly on when system is frozen (excessive hard disk use) -The reason the system freezes is because of high mem usage Tested on a Intel i5 520m with 4gb ram/ 4gb swap (Lenovo t410) Intel E6400 with 3gb ram/ 3gb swap This bug is really hard to deal with because it usually requires a hard restart. Please fix ASAP if possible
Update: Another user reported excess flash drive usage on high memory usage when booted as a live user. This means that swap is not the issue. The issue is completely with the system RAM management
Is this a 32-bit kernel or 64? You selected a hardware type of "IA-64"!
As far as I know, this bug effects all 64 bit linux kernels released since 2007
is there a more appropriate hardware classification? I only have intel 64 bit hardware to test with.
The ones listed are the kernels (as of today) that i've noticed the issue with
The computer also seems to freeze when the disk is being used a lot.
issue still occurs in the new kernels (4.16.11)
Also occurs in 4.16.12
High disk usage, or high memory usage seems to cause this issue. Swap puts both these issues together.
Still occurs 4.16.13. Please fix
This is a critical issue, and Linux desktop can never be stable on older hardware with a big issue like this. Recently, my Linux system crashed with 4 tabs of google docs open in Firefox, and VLC. The same issue does not occur in Windows(Ugh, Microsoft) but when this issue occurs, and system freezes completely, I am forced to go back to windows. Please fix this critical bug, and make me not have to touch windows ever again. I would greatly appreciate it.
Please provide more detail about your system configuration. lspci -v, cat /proc/scsi/scsi, etc (https://www.kernel.org/doc/html/latest/admin-guide/reporting-bugs.html#gather-information) I suspect your I/O subsystem simply can't cope with the load being thrown at it. It's *probably* seeks, but I don't know whether you're using an SSD or rotating storage.

Created attachment 276357 [details] Dmesg after boot
https://www.cnet.com/products/lenovo-thinkpad-t410-2522/review/ (with integrated graphics)
https://support.lenovo.com/sg/en/solutions/pd006109 this one is better. Just for you to get an idea of the hardware i am using.
It is the i5-520m version
This still occurs on kernel 4.17.2. If the isssue is a I/O subsystem overload, how can we fix this? The computer i'am using is relatively new, and it shouldn't require bleeding edge hardware to run linux properly without crashes when I have more than 6 firefox tabs open. I'm willing to run any test you want.
Update: I'd commented in detail about this bug in the other thread (https://bugzilla.kernel.org/show_bug.cgi?id=196729). I run the live versions of Linux on a 4GB Core-i5 laptop (and another 4GB pentium laptop also.) Just wanted to add: I've added 4Gb of RAM to the Core-i5 laptop for 8Gb total. With Fedora 28, the system will still cease up with maybe 2 dozen (or less depending on what's happening (video, etc) ) FF tabs opened/active. I came back here to note that, I'm currently using a Live Debian Stretch (9.5). There are obviously significant differences in the way these variants of Linux manage memory. Why? Because under the same system conditions (Gnome, same s/w programs installed and/or running), I can open WAY more tabs in FF on Debian; open more simultaneous programs, without fear of a sudden system heart-attack. In fact, it is much harder for me to cause the system freeze in Debian, even with approaching 50 tabs opened in FF developer 63... I understand there are underlying Fedora vs Debian system differences like: systemd vs init, and Wayland vs Xorg, Gnome versions (3.28.1 vs 3.22.5) and kernel revisions (4.16.3-301.fc28.x86_64 vs 4.9.110-1 (2018-07-05) ), but in all, I find Debian WAYYYY more forgiving, and more manageable, ESPECIALLY in light of this FATAL flaw, AND the known Gnome memory leak bug which can easily be remediated for in Debian by restarting Gnome (via Alt-F2, r) to free back up that memory. (The only way to accomplish this in Fedora is to actually log out of your session because of Wayland limitations.) Anyway, I jut thought it's another data point to add to the mystery. I still have to keep resource monitor opened even in Stretch, just in case, but I only crashed Stretch once over the past 3 months or so when I was in the 80's (mem % used) and let a video play for 2 hrs without checking up. Normally anyway, that percentage isn't rising above the 70's in my typical "working" environment. Finally, I'd like to mention to those asking for logs, etc., for this issue, realize that WHEN this issue occurs, it *is* essentially a heart-attack for the system. There is no recourse, and no way to gather logs. EVERYTHING ceases up- usually never to come back. A hard power-cycle is the only recourse, and NO logs which would shed light on the issue are written. EVERYTHING stops- including log writing. This is the reality. I *do* have a few logs from and old (non-live) Jesse 8.7.1 install-- for a few times when, the system did revive, after hours-- and there's nothing in there that would shed light on the issue. The few entries in the log that I've researched pointed to no other instances/causes of this same issue. It would be nice after 11 or 12 years of this issue, if someone higher up and more knowledgeable in the development "food chain" would would simply replicate the issue, it's not really that hard to do so at all. It honestly is a show-stopper. Ciao.
Now on Manjaro Linux 18.0.1 with the same laptop and 8Gib of ram. 1. Memory gets near full 2. Swap partition starts to fill 3. Swap gets 80% full 4. System freezes. Shouldn’t the OOM killer be killing processes? Why isn’t it? My laptop was frozen for 2 hours with constant hard drive writes. This behavior is not seen in windows on the same machine. I eventually had to hard restart. @Iou is right. It is a show stopper, and should have been fixed by now after being a bug for 13 or so years. When it happens, it is impossible to collect logs, even if I do something like top -b >top.log How to test: Bootup your favorite distro 1. Do something memory intensive, like compiling, something that will use all your ram. 2. Open some Firefox tabs. 3. Watch disk thrashing occur with no way to get logs. Hold down the power button when you are ready to try again.
If you like, I can open a new report with all the sys info in one place.
