Hello,

after upgrading to v6.6.24 from v6.6.23 some old boxes (i686; Intel Celeron
M) stop to boot:

They hang after:

Decompressing Linux... Parsing ELF... No relocation needed... done.
Booting the kernel (entry_offset: 0x00000000).

After some minutes they reboot.

I bisected this down to

    x86/mpparse: Register APIC address only once

    [ Upstream commit f2208aa12c27bfada3c15c550c03ca81d42dcac2 ]

The APIC address is registered twice. First during the early detection
and
afterwards when actually scanning the table for APIC IDs. The APIC and
    topology core warn about the second attempt.

    Restrict it to the early detection call.

Reverting this commit in v6.6.24 solves the problem.

Is this also an issue in 6.9-rc1 or newer or 6.8.3 or newer?


It is not an issue with 6.9-rc1. 6.9-rc1 just boots fine.
