Yes, I do have the latest kernel (circa this morning). Do you have any
other ideas about what can be wrong?
BTW, in the following lapic_ipi_raw call, is the last argument expected
to be 0 or maybe it's typo and it should be apic_id instead?
/* do an INIT IPI: deassert RESET */
lapic_ipi_raw(APIC_DEST_ALLESELF | APIC_TRIGMOD_LEVEL |
APIC_LEVEL_DEASSERT | APIC_DESTMODE_PHY | APIC_DELMODE_INIT, 0);
