| What happens if you also print the current mask register?  CBB_SOCKET_MASK?

Rebooted with xl0 card inserted,
first time (after initialization) mask=7,
after eject/insert xl0 mask=1.

Rebooted once more, without card.
After card (xl0) inserted, mask=1.

Rebooted with same card inserted in second slot.
First time (after initialization) mask=7,
after eject/insert into same slot xl0 mask=1,
after eject card was inserted into first slot, mask=1,

code was:
if (!ack) {
	mask = cbb_get(sc, CBB_SOCKET_MASK);
	printf("Need to ack %#x, mask=%08x\n", sockevent, mask);
	cbb_set(sc, CBB_SOCKET_EVENT, sockevent);
}

regards,
Ilya.
