Hi everyone, new user here in the forums but been using Endeavour since Antergos dropped support.
I’m having an issue with the latest kernel version and decided to try my luck here before trying other places. If this isn’t the right place to ask, just point me in the right direction and I’ll gladly head that way
As the title mentions, the system soft-lock after logging in ever since upgrading to kernel 5.15 (any patch version). After a few minutes I can’t interact with the taskbar or open new windows, and any command I run on the terminal that requires superuser privileges just hang. As mentioned, this happens after a few minutes.
Also most of the time when logging in, keyboard, mouse or both fail to register any input but weirdly enough, sysrq key combinations work even if the keyboard was not registering input.
My hardware is the following:
Ryzen 9 5950x
64 Gb Crucial Ballistix Ram
Vega 64 / RX 6900XT (for VM passthrough)
Asus Dark Hero motherboard
2x Corsair MP600 Force NVME 1TB disks
I’m using linux-zen kernel with KDE Plasma 5.23.4 (X11) and LightDM
Using kernel 5.14.16 makes the system usable again so I have downgraded the linux-zen package and headers to said version but still update the regular linux kernel package to test if things improve with newer versions.
I managed to get the output of dmesg before the system locked and I can certainly see many errors but not sure where to go from there. Here is a link for the full log, in case it helps
Feel free to ask for any other information that might be needed but for now I haven’t seen anyone having this issues.
(Thing like torrent traffic can play havoc with network adapters, particularly wifi.)
If 5.15 is having the issue then switching to 5.10 for the time being would get you a maintained kernel, and doing a kernel bisection between 5.14.16 and 5.15.0 could be useful to find the specific change that triggered the problem (which can then be reported to the kernel/driver developers).
Something that I forgot to mention is that I have a bridge network interface where I connect my physical network interfaces and the virtual network interface from my windows VM to have it in the same network as the host instead of using a NAT.
lsmod | grep r816
there is no output, but if a look for the previously mentioned driver (r8125) it’s properly loaded.
The only way I managed to get the 2.5gbps ethernet port to work was to install the driver mentioned (r8125) from AUR. Unfortunatedly I had already tested removing the package but all I got was a broken bridge network
So the driver is needed, but looks like it doesn’t work with kernel 5.15. Therefore, same options apply: use linux-lts until it’s fixed, report an issue to the upstream driver developers, bisect the kernel to find the offending change.
@jonathon not sure it’s driver related, because even without it the system locks, For now reverting to kernel 5.14 is working fine (need it for the amdgpu hotplug fix that was added) but also installed LTS kernel to be on the safe side.
As much as I’ve been daily driving linux for quite a few years, I’ve never bisected the kernel before since it’s been quite stable (up until now). I will give it a try (google surely knows how) but any pointer to the right documentation would be great
In any case, thanks for the help, really appreciated
