The dmesg output is for the FC6 distro kernel > 2.6.18-1.2689.fc6PAE, but I see the same symptoms with 2.6.18-mm1. You must see difference with mm1 (suppose that mm1 already includes the latest ALSA patches). When the CORB/RIRB interrupt gets broken, the driver first switches to poling mode, then single_cmd mode as fallback. Also, try disable_msi=1 option for mm1. MSI seems broken on some systems.
