From my naked eyes, I can sense that the interrupt was trigered during/before sampling rate calibration, and since the calibration expect to not trigger any interrupt, this will cause unexpected behaviour especially for this MPSAFEed driver *and* during boot. Besides, the pcm construction also done before the calibration, unlike snd_atiixp where the hook is use to bring everything alive after the necessary step is finished. I'll come up with something shortly. -- Ariff Abdullah FreeBSD --Signature=_Tue__28_Feb_2006_04_37_35_+0800_gFTfwEp=RsaQgedK Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.1 (FreeBSD) iD8DBQFEA2MUlr+deMUwTNoRAqUfAKCvKGnyl9ImXH8N/bQiLVTx9Kam9wCg2IQZ He2E9248KLSdErm1qjHBj4o= =ZCh3 -----END PGP SIGNATURE----- --Signature=_Tue__28_Feb_2006_04_37_35_+0800_gFTfwEp=RsaQgedK--
