description |
My main server has been running into hard lockups about once a week ever since I switched to the 4.15 Ubuntu 18.04 kernel.
When this happens, nothing is printed to the console, it's effectively stuck showing a login prompt. The system is running with panic=1 on the cmdline but isn't rebooting so the kernel isn't even processing this as a kernel panic.
As this felt like a potential hardware issue, I had my hosting provider give me a completely different system, different motherboard, different CPU, different RAM and different storage, I installed that system on 18.04 and moved my data over, a week later, I hit the issue again.
We've since also had a LXD user reporting similar symptoms here also on varying hardware:
https://github.com/lxc/lxd/issues/5197
My system doesn't have a lot of memory pressure with about 50% of free memory:
root@vorash:~# free -m
total used free shared buff/cache available
Mem: 31819 17574 402 513 13842 13292
Swap: 15909 2687 13222
I will now try to increase console logging as much as possible on the system in the hopes that next time it hangs we can get a better idea of what happened but I'm not too hopeful given the complete silence on the console when this occurs.
System is currently on:
Linux vorash 4.15.0-36-generic #39-Ubuntu SMP Mon Sep 24 16:19:09 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
But I've seen this since the GA kernel on 4.15 so it's not a recent regression. |

== SRU Justification ==
When using zram (as installed and configured with the zram-config package)
systems can lockup after about a week of use. This occurs because of
a hang in a lock in zram.
== Test Case ==
Run stress-ng --brk 0 --stack 0 in a Bionic amd64 server VM with 1GM of
memory, 16 CPU threads and zram-config installed. Without the fix the
kernel will hang in a spinlock after 1-2 hours of run time. With the fix,
the hang does not occur. Testing shows that with the fix, 5 x 16 CPU hours
of stress testing with stress-ng works fine without the lockup occurring.
== The fix ==
Upstream commit c4d6c4cc7bfd ("zram: correct flag name of ZRAM_ACCESS") as
a prerequisite followed by a minor context wiggle backport of the fix with
commit 3c9959e02547 ("zram: fix lockdep warning of free block handling").
== Regression Potential ==
This touches the zram locking, so the core zram driver is affected. However
the fixes are backports from 5.0, so the fixes have had a fair amount of
testing in later kernels.
