Hello,


Also see if other things are relevant for you from forum search

My kernel is 5.5

#4

It's hard to say, but I'd start by testing every kernel from 4.19 and above including the real time kernels.

I would also be sure your bios is up to date and also disable IPv6.

#5

Thank you
Then there're two things
How to make sure my bios is up to date?
And how to disable IPv6?

#6

Bios: Obtain Motherboard Make and Model number - go to 'Make' website, select 'model number', check latest Bios release version against your Motherboard. If higher download and install.
IPV6 disable in Network settings. Select IPV6 and set to Ignore from dropdown list.

You could also try this:

Add the following kernel boot parameters to grub:

ipv6.disable=1 pcie_aspm=off net.ifnames=0

The following command will automatically add the above kernel boot parameter to /etc/default/grub:

sudo cp /etc/default/grub /etc/default/grub.bak && sudo sed '/^GRUB_CMDLINE_LINUX_DEFAULT=/s/"$/ ipv6.disable=1 pcie_aspm=off net.ifnames=0"/g' -i /etc/default/grub

After adding the boot parameter(s) and saving your changes, run:

sudo update-grub

Reboot, and test for improvement.

These chamges can be helpful even if they don't appear to resolve your issue.

I would reccommend leaving the changes in place, but you can easily restore the file to its original state with:

sudo cp /etc/default/grub.bak /etc/default/grub

After restoring the file, again run:

sudo update-grub

Then reboot.
