ACPI IRQ storm with 6.10

[Jiri Slaby <jirislaby@xxxxxxxxxx>]

Hi,

one openSUSE's user reported that with 6.10, he sees one CPU under an 
IRQ storm from ACPI (sci_interrupt):
   9:   20220768          ...  IR-IO-APIC    9-fasteoi   acpi

At:
https://bugzilla.suse.com/show_bug.cgi?id=1229085

6.9 was OK.

With acpi.debug_level=0x08000000 acpi.debug_layer=0xffffffff, there is a 
repeated load of:

Longer (yet still trimmed due to pace of the messages) log:
https://bugzilla.suse.com/attachment.cgi?id=876664

Any ideas?
