Thanks for the report, but the single line of dmesg w/o any context is not
really helpful. Can you please provide a larger piece of dmesg which shows
in which context this happens.

I assume that this happens during early boot right when CPU1 is brought up,
right?

Borislav is seeing similar issues on larger AMD machines. The interrupt
seems to come from BIOS/microcode during bringup of secondary CPUs and we
have no idea why.

Thanks,
