hi I ran it , but the setting of the device has changed as I changed to NetworkManage instead of networkd with which the original pug was reported ,as I added (Samsung SSD 980 PRO 2TB (5B2QGXA7)) to my pc after which the pc wasn't able to connect at all.
after converting to NetworkManage luckily it connected for more than a day then disconnected and didn't reconnect without a restart

now I thought it may be caused by the bridge connection or networkd but i think the same problem still exist with NetworkManage

but some thing may happened between the new ssd and networkd may be

this is the new dmesg:

While the bug report is for LoongArch, there are comments about issues on x86 as well.

Can you add 'pcie_aspm=off' to the kernel commandline and let us know if that makes a difference?

I'll change it and let you know if something is different.

I did the following
- ran sudo nano /etc/default/grub
- changed
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=off"
saved the changes
- ran sudo update-grub
the network was off when I did that so I restarted the system and the network disconnected again within mins

I ran 'sudo sysctl -a | grep pcie' and there is no output i ran pcie_aspm=off then no output again for 'sudo sysctl -a | grep pcie'

is there something I am doing wrong here ?

This is not a sysctl so you want see it there. Try:
$ cat /proc/cmdline

And post the output of dmesg.

thanks for your help the network disconnected again within half an hour I restarted the pc this is dmesg after restart

I deleted dmesg outbut so it do not distract any one 'sudo journalctl -b -1' output is at comment #43

"Fixed with kernel v6.4.7". If so, what to do with 6.2?..

great news thanks,
should we upgrade kernel or wait for ubuntu 23.10 ?

There seems to be two issues. For those affected, can you please post the output of `sudo journalctl --dmesg | grep r8169`?

Your NIC is a chip 46. From the kernel source:

drivers/net/ethernet/realtek/r8169_main.c: [RTL_GIGA_MAC_VER_46] = {"RTL8168h/8111h", FIRMWARE_8168H_2},

So likely this since `pcie_aspm=off` helps somewhat:
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=90ca51e8c654

I've built a test kernel with the referenced fixes:
https://kernel.ubuntu.com/~juergh/lp2031537/

Can somebody test it please? Note that it's an unsigned kernel so you need to temporarily disable SecureBoot in the BIOS to be able to boot it. Install linux-image-unsigned, linux-modules and probably linux-modules-extra.

Let us know if that fixes the issue.

Hi @Juerg,
thanks a lot,

Ah rats. You need to remove linux-image-6.2.0-32-generic first:

$ dpkg -r linux-image-6.2.0-32-generic

I do not know how this happend my kernel was 31 not 32

should I move to 6.5 directly if the fix is there already

any way I ran dpkg -r linux-image-6.2.0-32-generic

OK. We can force remove that package temporarily but need to fix the system again after you've tested the kernel.

$ dpkg -r --force-depends linux-image-6.2.0-32-generic
$ dpkg -i linux-image-unsigned-6.2.0-32-generic_6.2.0-32.32+lp2031537_amd64.deb

Then check:
dpkg -l | grep lp2031537
ii linux-image-unsigned-6.2.0-32-generic 6.2.0-32.32+lp2031537 amd64 Linux kernel image for version 6.2.0 on 64 bit x86 SMP

ii linux-modules-extra-6.2.0-32-generic 6.2.0-32.32+lp2031537 amd64 Linux kernel extra modules for version 6.2.0 on 64 bit x86 SMP

how can I fix the system after that ?

may I change the driver away from nvidia this way there is no dependencies

Afterwards remove all the installed lp2031537 packages and reinstall 6.2.0-32.32 from the archive. Something like:
$ dpkg -l | grep lp2031537 | awk '{print $2}' | xargs sudo dpkg -r --force-depends
$ sudo sudo apt install --reinstall linux-image-6.2.0-32-generic

Then check:
$ dpkg -l | grep linux-

And verify that all the packages are 'ii'.

thanks @Juerg Haefliger,
I hope I am booting the right kernel now

That looks good. Reboot and select the kernel in grub and then check with 'uname -a'. Don't forget to disable SecureBoot first (in the BIOS).

thanks @Juerg Haefliger,

I am on the test kernel now with pcie_aspm=off for 19 hours : 15 mins hope the network never let me down again I will modify this comment if any change happened

Remove 'pcie_aspm=off', that should not be necessary anymore.

thanks @Juerg Haefliger I reversed my comment #38 I want it to be up for as long as possible to test it so if I don't have to I will keep is running till the next reboot when pcie_aspm=off would be removed

The test is meaningless with 'pcie_aspm=off`. The test kernel has to work without that parameter and if it doesn't it means the fix is no good. Please test without the parameter.

done @Juerg Haefliger I restarted the pc will monitor and update this comment if any thing happened

Hi Juerg,

Just wanted to report that the test kernel is working for me -- I had the exact scenario described in duplicate #2031448 that was folded into this bug#.

this session was up for around 25 hours , I wanted to make it up for longer to test but the electricity gone down , I hope it is enough to test the fix I will post any problem if detected

the ups is not working the electricity went out again but during the time it was up there is nothing different than appove , I hope I can test it for longer period

I hope the fix will be merged soon with the the kernel

Dear Team,

   Any news? When will release the official update for this issue? Or need to fix it manually?

   Thank you

Dear @Larry,

I tested the kernel in comment #78 and the bug didn't show up again it is a test kernel , but Garry in comment 70 mentioned it is fixed already in kernel 6.4 I have no problem keeping the test kernel till ubuntu 23.10 release with kernel 6.5

Patches are in the pipeline:
https://lists.ubuntu.com/archives/kernel-team/2023-September/142665.html

You just need to wait until an updated kernel falls out on the other side. SRU release schedule:
https://kernel.ubuntu.com

Dear Team,

   I'm looking for update on ubuntu 22.04, if there have no plan to update this, I need some quick solution...

   Or rollback to kernel 5... or please provide how to migrate kernel to 6.4 or 6.5 on 22.04

   Thank you

This will automatically roll back into the 22.04 HWE kernel. There's no quick solution other than running an unsupported test kernel or the GA 5.15 kernel.

I had the same issue. I changed ASPM to disable in BIOS and now issue gone.

This bug is awaiting verification that the linux/6.2.0-36.37 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-lunar-linux' to 'verification-done-lunar-linux'. If the problem still exists, change the tag 'verification-needed-lunar-linux' to 'verification-failed-lunar-linux'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

hi all,

when I changed setting to get pre release the kernel wasn't there yet

I downloaded those files

linux-headers-6.2.0-36_6.2.0-36.37_all.deb
linux-headers-6.2.0-36-generic_6.2.0-36.37_amd64.deb

from https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa/+build/26751907

ran sudo dpkg -i *.deb in the file I created specifically to put them in

this is my running kernel now I hope it is all okay

I monitored for 3 days with no problem I changed the tag so that the change don't drop automatically the bug may appear after longer period if so I will change it

6.2.0-34-generic (release)
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash fsck.mode=force fsck.repair=yes pcie_aspm=off"

When the driver fails, NetworkManager shows "active (running)" and /sys/class/net/enp2s0/speed shows "1000" :-(
