Talos II / Re: Petitboot lock after Fedora 36 update
« on: December 12, 2022, 03:24:28 am »
A tough question I think ...

It looks to me that the skiroot 5.5-based kernel isn't able to cope with some situations where an XFS filesystem written by much newer kernel can be left in.Thus the solution could be to switch to upstream PNOR firmware builds which is using 5.10 kernels (still quite old, no development for p9, a little bit for p10 ...). Should be doable for Blackbird, there is some old work in progress for Talos from me. I agree the safe way around is to avoid XFS (and/or btrfs) for the host OS rootfs or /boot and rely on ext4. I think the mis-behaviour won't be ppc64le specific, but it's uncommon to use 5.5 kernel to read a filesystem written by a much more kernel ...

And how to recover from the failure without a physical access. If there would be a way to set a host's nvram variable from the BMC, one could disable the xfs module for the skiroot kernel and boot from another media.

Or you can use mesa-freeworld from RPM Fusion. It should complement the reduced mesa from Fedora.

That's an awesome news! Now to keep watching it if it continues to work in the future. But this is an important milestone. I would suggest to use to get all the RCs for the upcoming kernel even when running stable Fedoras. I have it enabled myself and it has already proved useful.

yeah, 0.9 GB/s is quite low, what does "sudo lspci -vv" say about "Link speed" for the SSD device?

For the record, I am getting 1.4GB/s (via hdparm -t) on my Samsung SSD 970 EVO Plus 1TB connected via PCIe 3.0 switch card.

It looks to me that mine "9128" is a different generation than yours 9215/9235, it might explain the different behaviour.

I suspect the way out is to pinpoint the issue to a specific kernel version(s) and then bisect ... AFAIK the AmigaOne people are running into similar kind of issues as the mainline kernel changes and the kernel maintainers are listening to them.

Also, can the start of these messages/errors be tied to a specific kernel version? What are your the SATA controllers?

I have searched thru my whole journal and there is no such message. My SATA controller is Marvell 88SE9128 (RAID controller with HyperDuo) with a SATA SSD (the on-board Adaptec SAS controller didn't like it much) and an optical drive connected.

Operating Systems and Porting / Re: New Kernel 5.16 and new problem

Seeing if @sharkcz knows anything about it.
hmm, says me nothing, but is it reproducible? I believe a standard kernel shouldn't have problems executing VMX instructions ...

It has been done recently during the F-36 mass-rebuild and it's a mess :-) But we are fixing the bugs that have been discovered ...

Hi Sharkcz, so you too have noticed that changes have been made starting from version 5.14 onwards, which have affected the functioning of AMD GPUs. Is it possible to hope for a correction in good times of this problem in the Linux Kernel by the Kernel team? I had written about the problem, already at the beginning of version 5.14 and therefore I tried to make everyone aware of this problem but at the time, unfortunately few followed me ...
5.14 was OK for my WX4100, the breakage came with 5.15 rc1

The highest chance to get amdgpu driver issues fixed is to report them in the AMD bug tracker ( with an information what particular commit caused the issue (identified using the bisection process).

grub is using the GRUB_CMDLINE_LINUX variable defined in /etc/grub/default to set the default value of the kernel parameters for the host Linux

@ClassicHasClass, no output during petitboot, but the aspeed's HDMI does. The card's backlight LEDs for its logo *do* light during petitboot but then go out on boot. I seem to recall they used to stay on when the card was working.F35 is Wayland without the xorg option that earlier Fedoras had.

@sharkcz, I'm really, really hoping to not have to go down any sort of a kernel compiling rabbit Hole.

It's not that bad, I was worried myself :-) I would suggest to start with the drm-next-5.14 branch from the AMD tree and it should be ~10 iterations.

For the record, you might hit on a Polaris card starting with 5.15

If you know the version that worked and what does not, then you can bisect. In this case the iteration times would be short, mine was 1 iteration in a day for the bug above ... If you want a "minimized" kernel config derived from the Fedora one which reduces the compile times significantly, let me know. If you need help about bisecting, I can provide that too :-)

So at least some good news after the recent fixes :-)
