Thanks. So I installed 18 LTS again. A major PITA, but I used 18 LTS on
this laptop for 2 full years without a problem. Always fully upgraded,
so with all the standard permutations of kernel, modules and firmware,
on lots of different wifi networks. There was never a single issue. Nor
under 16.10
Why not try a 19.10 livecd?
Or you could try get the old firmware from the linux firmware git and
use a 4.x kernel and see if the problem disappears.

But how would the live CD change anything? I'm on exactly the same
version as the live CD right now (20.4.5).
What I *know* is that my system was stable on 20.4.1 from two years ago,
i.e. that version of the kernel, modules, and firmware.
So how would I go about reverting to it (and blocking

Title:
ath10k_pci failed to wake target
Ideas, anyone? (Driving me crazy - 5 crashes this morning.)
This is basically a virgin Ubuntu 20 LTS. My laptop had no problems with
20 LTS until about a year ago. To exclude hardware failure as the cause,
my idea is to get the software back to the state it was in a year ago.
Is that reasonable?
@kaihengfeng I try to use only the most vanilla setup, so yes, it has
happened with all the mainline Ubuntu kernels coming from 20 LTS
upgrades over the last year and also 22.10.
Suspend is disabled, I guess by kernel parameter `pcie_aspm=off`, by
`HandleLidSwitch=ignore` in
Does mainline kernel have this issue? Does the issue only happen when
system come out of suspend?

Interesting. Yes `pcie_aspm=off` is already in the grub parameters but
not `pcie_port_pm=off`. I will add that now, wait for the daily crash
and then report back in due course.
Thanks.

If there is an issue with power management, the only other thing I can
think of is to disable power management in PCIe.
If you pass the kernel parameters pcie_aspm=off and pcie_port_pm=off I
think this would achieve this.
In your output of `sudo lshw -C Network`, there is “capabilities: pm”,

Just the usual "failed to wake target", sometimes accompanied by
"firmware crashed!", but always requiring a full reboot to fix.
BUT occasionally it even "sleeps through" the reboot and requires a
second reboot! In fact this was what happened last time, yesterday.
Here's the dmesg:

Hello thedoctar.
As mentioned, I had 22.10 installed with latest repo-provided firmware.
That's pretty recent isn't it?
I also tried a surgical downgrade of the ath10k firmware to a version
corresponding to 20 LTS. Crashes continued.
I tried removing the firmware6.bin file which forced "API5"
Did you try upgrading to upstream firmware:

Hi Alexandre,
Try it! But download the linux-firmware.deb package in case it doesn't
work, Then you can just re-install the older firmware.

I don't really want install the newest kernel, do you think it can work without

Hi Alexandre,
Yes I manually installed the latest firmware from the link above.
Just extract the contents to /lib/firmware and override.
I also installed the latest kernel. (currently 5.8:

It looks like I'm affected by this issue too. I loose connection and have to

@thedoctar how did you solve it? Did you manually I install the latest
firmware? My system is fully updated but nothing helps.
