Hi all, I'm currently running on Ubuntu Dapper and xen 3.0 testing. I noticed my sound card didnt work. I looked in dmesg and found this: Apr 9 17:49:29 phoenix kernel: [ 27.490852] architecture does not support 28bit PCI busmaster DMA Grepping the kernel I came up with this, from sound/pci/ice1712/ice1712.c: /* check, if we can restrict PCI DMA transfers to 28 bits */ if (pci_set_dma_mask(pci, 0x0fffffff) < 0 || pci_set_consistent_dma_mask(pci, 0x0fffffff) < 0) { snd_printk(KERN_ERR "architecture does not support 28bit PCI busmaster DMA\n"); pci_disable_device(pci); return -ENXIO; } I commented it out, and the module loaded but I got a burst of static from the speakers. I suspect that this code is incompatible with Xen. Why does Xen not allow the dom0 to set these parameters? My development workstation is my main home box, and I like to have sound on it.
