DESCRIPTION

     The eso device driver supports sound cards based on ESS Technology Solo-1
     PCI AudioDrive chips (ES1938 and ES1946), e.g. the TerraTec 128i PCI
     card.


DIAGNOSTICS

     eso0: can't map Audio 1 DMA into I/O space  PCI autoconfiguration did not
     map the first audio channel DMA controller into I/O space at a suitable

     playback functionality will be available.

     eso0: reset timeout  The device failed to acknowledge being reset.

     eso0: RDR timeout  The driver timed out reading data from a controller
     register.

     eso0: WDR timeout  The driver timed out waiting to send a command or
     writing to a controller register.
