No the computer only boots if I add mitigations=off… I haven’t added it permanently yet.
Did you install the headers?
Okay sorry i misunderstood. I’m finding it strange that my system boots fine except on virtual box.
I missed the word without.
No I hadn’t, this is the error I got when I just tried it -
==> dkms install --no-depmod vboxhost/6.1.36_OSE -k 5.10.134-1-lts510 Error! Bad return status for module build on kernel: 5.10.134-1-lts510 (x86_64) Consult /var/lib/dkms/vboxhost/6.1.36_OSE/build/make.log for more information. ==> WARNING: `dkms install --no-depmod vboxhost/6.1.36_OSE -k 5.10.134-1-lts510' exited 10
No you hadn’t what?
Last night when I installed the linux-lts510, I didnt install the headers.
Well you would need to install the headers for that specific kernel.
Removed virtualbox virtualbox-host-dkms, installed linux-lts510-headers. still no luck.
Check the error above, modules were failing to build and the error showed it was vboxhost… so i removed virtualbox for now to see if the kernel headers would build and install. They did but it doesn’t change the outcome with failed boot.
Funny thing is I am sure that this is because of some changes in the recent version. And I thought LTS would be immune to being borked by changes. 5.15.55 worked. it’s still in the cache but I dont know how advisable it is to go back and to stay at that version indefinitely.
I also had this clocksource problem that affects AMD cpu’s, but with the 5.18.15 kernel only.
Kernel 5.18.14 and the LTS booted fine.
I had to add
spectre_v2=off to the kernel boot string to fix it.
Ahh read through that thread and I am glad I am not the only one… Looks like the fix is in the works and I will just temporarily add the mitigations workaround till the next updates…
There is a mention of
retbleed=off in that thread from ArchForum as well.
Has anyone tried that?
CPU: Info: model: AMD Ryzen 7 4800U with Radeon Graphics bits: 64 type: MT MCP
Type: retbleed mitigation: untrained return thunk; SMT enabled with STIBP protection
uname -r 5.18.15-zen1-2-zen
It is not hit by this issue on this machine on my end.
I have the same issue since I updated 5.10 last weekend. At first I thought the latest kernel works but after an update it stopped to boot to UI as well.
Thx for the work-around. It works fine.
I hope they will fix it soon.
Looks like linux 5.18.16.arch1-1 currently in testing should have a fix for this issue:
Man I panicked more than any kernel seeing this
I’d suggest that pebcak’s post just above should be marked as the solution.
Jonathons Lts-Kernel 5.10.135 works again fine.
