Hi,
I have tried replacing the old IDE layer on my dual P4 machine with the PATA driver instead, but
the CDRW drive on the second IDE bus (the old /dev/hdd drive) is never recognised:
ata1: PATA max UDMA/100 cmd 0x000101f0 ctl 0x000103f6 bmdma 0x0001ffa0 irq 14

The DVD-ROM drive on the same PATA controller is still found correctly (fortunately), once the
ata_piix driver gives up and disabled the misbehaving drive.
I have tried setting both atapi_dmadir=1 and fua=1 with the libata module, to no effect.
The CDRW drive works fine with the old IDE layer, but modern distros seem to be forcing everyone
down the PATA route. Can anyone suggest why the PATA layer hates my CDRW drive so much, please?
For reference, this is what the old IDE layer used to say:

Thanks,

(P.S. It's not just 2.6.21.3 that is unable to activate this drive. Both FC7 and Ubuntu 7.04 have
exactly the same problem.)
