Linux on old hppa c3000, dvd ide found..but not avaliable
I run Debian SID on HPPA C3000, a very old workstation from HP.
I have this problem, the ide cd-drom drive seems to be recognized, but no device created.
The dvd is recognized:
dmesg |grep -i dvd
[ 34.066904] ata1.00: ATAPI: ATAPI DVD+RW 4X4X12, B1GY, max UDMA/33
but no device is created!
cdrecord -scanbus
wodim: No such file or directory.
Cannot open SCSI driver!
For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.

I try to modbprobe pata_legacy and machine go to kernel panic.
edit1: checking dmesg I see errors..

is my unit failed?
Solution found.
The c3000 manual (which refer to HPUX mainly, not Linux)
report to set "cable select" for cd-rom ide.
But if I set to cable-select report the error on first post
and don’t work.
I set it as master and..
dmesg |grep -i ata

ls /dev/sr0
/dev/sr0
cd-info and lsblk report the drive.
So solution found.
