: [ee01c4d72adffb7d424535adf630f2955748fa8b] Merge branch 'akpm' (patches
from Andrew)
git bisect bad ee01c4d72adffb7d424535adf630f2955748fa8b
# bad: [16d91548d1057691979de4686693f0ff92f46000] Merge tag 'xfs-5.8-merge-8'
of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
git bisect bad 16d91548d1057691979de468669
And the bisect between 5.4.78 (good) and 5.8.18 (bad).
The following results with the mainline kernel
v5.8.18/FAIL
v5.8.4/ FAIL
v5.8-rc5/ FAIL
v5.8-rc1/ FAIL
v5.7.19/PASS
v5.7.18/PASS
v5.7.16/
So bisecting between 5.8.18 (bad) and 5.11-rc3 (good).
The following results with the mainline kernel
v5.11-rc3/ PASS
v5.9.12/PASS
v5.9.10/PASS
v5.9.9/ MISSING
v5.9.8/ FAIL (could not boot long enough for full test)
v5.9.
OK, so using https://people.canonical.com/~kernel/info/kernel-version-
map.html that states that Ubuntu kernel 5.8.0-36.40~20.04.1 matches
mainline version 5.8.18. I have installed 5.8.18 and it fails ! So it is
not the Ubuntu patches.
Ubuntu Kernels:
linux-image-5.4.0-59-generic: PASS
linux-image
@kaihengfeng
I have found that running the command "fio --name=basic
--directory=/path/to/empty/directory --size=1G --rw=randrw --numjobs=4
--loops=5" runs fine on linux-image-5.4.0-59-generic but when trying
with linux-image-5.8.0-36-generic it would freeze the system in the
"Laying out IO file"
FYI I have captured the `sudo lspci -vv` output on the kernel 5.8
*before* the issue here https://pastebin.ubuntu.com/p/GtZyTWzKTd/ it is
subtly different to the 5.4 kernel (which has not had the issue) in case
that mattered.
I was also able to reproduce the issue again by causing high disk I/O,
s
Note for me it is happening quite rapidly (sometimes after 5-10 minutes)
of high disk load. Eg the first times it happened when apt was running
update-grub and then when pip3 install was running. Then to capture the
logs above i started a `find /` and `find ~` at the same time and this
was enough t
@kairhengfeng Yes this is a regression after the upgrade from 5.4 to
5.8. After the upgrade I had it multiple times and now I have switched
back to 5.4 my machine is stable again.
I do not think I can run `lspci -vv` *after* the issue happens, as my
NVMe drive goes read-only, so all commands fail
I'm on Ubuntu 20.04, and after updating to the HWE 5.8 kernel recently I
have also been suffering my nvme drive becoming read only after a period
of time. I have now switched back to the 5.4 kernel and not suffered the
issue again.
I am on a single disk system so had to run dmesg --follow remotely
to ctrl-alt-F2 quick or hard
boot.
Let me know. I hope it tells me if there's replies.. (will look a bit)
might try pull the wifi.. but wanted to do some stuff.. but have much
more critical todo anyway.
Cheers - Andrew

I did it! I have connected AOC both with HDMI and D-SUB VGA cables.
Monitor AOC has PIP (picture in picture) option. So, my notebook think
that two monitors are connected. And boots ok!
