It did indeed!

I'll rebuild one or two of the servers with 20.04 LTE and report back.

As it only infrequently manifests, it will take a while to see whether
that fixes the issue.

[Bug 1928405] Re: mkdir/rm/sleep/ls causes kernel 'BUG: unable to handle kernel paging request'

2021-05-13 Thread Chris Guiver
Thank you for reporting this bug to Ubuntu.

Ubuntu 16.04 (xenial) reached end-of-life on April 29, 2021.

See this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We appreciate that this bug may be old and you might not be interested
in discussing it any more. But if you are then please upgrade to the
latest Ubuntu version and re-test. If you then find the bug is still
present in the newer Ubuntu version, please add a comment here telling
us which new version it is in.

FYI: You're also referring to unpatched and outdated kernels for
xenial/16.04. If you tried a patched kernel the issue may no longer have
existed (fyi: last xenial kernel was 4.4.0.210.216 available using
standard support which has now ended).

Typo: should be:

About half of the logs show tainted (G, D) and *HALF* untainted.

These computers are rebooted perhaps once a month, typically by power
failure.
