Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Nikola Kovacs (nx)]

It's a clean install. I barely managed to install it though. There are no other versions of the kernel in the repository.

I'm going to try the mainline kernels.

[Nikola Kovacs (nx)]

(My previous comment was too long, so I moved the logs to the end.)

The 4.13.0 mainline kernel is unusable, it panicked once immediately after boot, the second time it hung on the boot splash, the third time when I tried to open this page in firefox.
There was also an oops before the third hang, and that's the only thing present in kern.log [1]

The ubuntu kernel (4.13.0-12) seems more stable now than the one on the beta2 live usb, I still get some oopses in the log, and one managed to hang firefox completely (not even killall -9 firefox would kill it, and I had to hard reset, because it oopsed again during reboot), but no complete hangs yet. E.g.: [2]

No hangs yet with 4.14-rc2 mainline, but I did get an oops in kern.log: [3]

I'll try stress-testing 4.14.

[Nikola Kovacs (nx)]

Got an oops with 4.14 that hung firefox (like the ubuntu 4.13 kernel), had to hard-reset because the restart process couldn't kill my session.

The 4.14-rc2 mainline kernel has some other bugs: network-manager can't get an ip via dhcp, I have to manually run sudo dhclient (sometimes multiple times) to get an ip, and my syslog is full of these apport errors (I have to kill cups-browsed to stop it):

audit: type=1400 audit(1506762106.935:92): apparmor="DENIED" operation="create" profile="/usr/sbin/cups-browsed" pid=891 comm="cups-browsed" family="unix" sock_type="stream" protocol=0 requested_mask="create" denied_mask="create"

Just a comment from a security module developer.

What happens if you pass security=none to kernel command line options
(i.e. disable AppArmor security module), for I think it might help
isolating the problem because you are hitting oops at
security_vm_enough_memory_mm() and security_file_free().

Also, can you afford try compiling the kernel with KASAN enabled
(i.e. CONFIG_KASAN=y), for it might be some memory corruption error
(including possibility of use-after-free bug) ?

[Nikola Kovacs (nx)]

I tried security=none, it didn't help. I also tried the ubuntu-gnome 17.04 live-usb, and it panicked on boot.

I ran memtest and found that one of my memory sticks was defective. However, I still have some problems with only two sticks that did pass memtest.

This is with the 4.13 ubuntu kernel:

I tried Fedora Rawhide (26's nouveau doesn't work with my graphics card), with kernel 4.14.0-0.rc2.git4.1.fc28.x86_64, repeatedly starting atom and chrome is the easiest way to trigger it.

I also tried security=none and disabling hyperthreading (even though I should have the microcode fix for the Skylake/Kaby Lake HT bug) on Ubuntu's 4.13 kernel, it didn't help.

Here's the Fedora log:

Turns out I did not have the latest bios despite what Asus's wonderful Windows autoupdate utility claimed. I manually downloaded and installed the latest bios, which contains an Intel microcode update, and I haven't had a single crash since.

I even had the intel-microcode package installed, but it looks like the bios has a newer microcode.

Thanks for your help and sorry for the false alarm.

Closing invalid as a bios update resolved the issues.
