[POWER8] Flags mismatch error on boot. about archpower

[kth5]

Be aware that only POWER9 and up is supported and tested in powerpc64le. For POWER8 and below, may I recommend the powerpc64 variant.

With that said:

Can you boot with the option Arch Linux POWER Install (serial hvc0 as console)?

Does it also produce the same problem?

Then, it looks like it's falling back to the hash table based MMU instead of Radix. In theory that should be fine though.

[BushyToaster88]

Using the serial hvc0 as console option produces the exact same error. I tried the powerpc64 also does the same thing

[kth5]

I'm currently building a new linux-ppc64 with many more IBM pSeries specific options enabled including the native Hypervisor early console. So assuming you're running an LPAR here, this may help and give some more insight potentially.

This all will come up as a new ISO in a bit.

[kth5]

New ISO here based on linux-ppc 6.6.4:

https://archlinuxpower.org/iso/beta/archpower-2023.12.05-powerpc64.iso
https://archlinuxpower.org/iso/beta/archpower-2023.12.05-powerpc64.iso.sig

I do not have access to any pSeries machines and am limited to a POWER9 PowerNV via Raptor's Blackbird and then emulation. I really hope we can get some more insight, it just works (tm) or receive patches. :)

[BushyToaster88]

It seems to fail the same, heres the whole kernel boot process.

If you want I can give you a VPN which will give you access to the servers serial console plus the HMC/ASMI. Gentoo, Alpine and Ubuntu all have the same issue, though on the PPC64LE. If this can get fixed hopefully it can fix the error on both little and big endian.

[kth5]

From what it looks like your boot already is inside the initramfs as indicated by [ 1.610118] Run /init as init process. It is probably trying to probe hardware here and fails. I've seen this stage hang for up to 20s on a DP G5 before any life would be visible again on screen/serial.

I couldn't ask for access to the equipment but it would be highly appreciated.

[BushyToaster88]

I let it run for a little longer and it just repeats the flags error. Also what did you mean about the last thing you said. Did you want access to the equipment? I just dont understand what you meant sorry lol.

Yes, temporary access would be nice. I'm not sure when exacly I can find the time for a session though since I have not yet worked with the equipment before and thus would probably need a bit of a intro here on how you operate things.

I'm in TZ=Europe/Berlin, perhaps we could find a slot we both are available?

Im in Melbourne Australia so AEDT. I'll email you with the access details and how to navigate the server.

Fixed in linux-ppc64-6.6.4.arch1-3 which is in [testing] already now. ISOs for powerpc64 will follow.

We have a IBM S824 all set up now.

The problem was caused by the following kernel option:
CONFIG_HVC_OLD_HVSI

New ISO:

https://archlinuxpower.org/iso/stable/archpower-2023.12.07-powerpc64.iso.sig

Will prepare a new full release shortly.

Went through testing the new ISO and kernel on Discord with @BushyToaster88. Changes are confirmed working well.
