Please try this patch instead. Thanks, much better now: both HDD and CD-ROM seem to work on DTC and non-DTC chips. I get many of these messages with CD-ROM: [ 912.397076] generic_NCR5380_pread: No end dma signal (4096/4096) [ 913.141225] generic_NCR5380_pread: No end dma signal (4096/4096) Maybe just remove this error message as in my original patch? -- Ondrej Zary
