Same problem with both alpha6 and nightly 20080311
I have similar HW: ASUS A8N SLI deluxe (nvidia nForce4 CK804) ; AMD64 3500+ ; Philips DVDR1640 ; nvidia 6600GT (NV43)
Suspect DMA issues on that HW combination
notice that I'm using the hardy kernel 2.6.24-8 (32 bit) from backports on my gutsy 7.10 with much satisfaction...
Not tried the all_generic_workaround_yet
