Like I promised here is the status update for the Pioneer DRM-604X changer.
Today I finally got hold of the new (well, newer) firmware roms. I'm running
it on a -current of a couple of days ago.
It is now at:
/kernel: cd4: <PIONEER CD-ROM DRM-600 2404> Removable CD-ROM SCSI-CCS device
(when set to non-SCSI2 mode via the dipswitch on the back)
or
/kernel: cd3: <PIONEER CD-ROM DRM-604X 2404> Removable CD-ROM SCSI-2 device
(when set to SCSI-2 mode).
The problem:
May 7 20:53:10 p100 /kernel: (cd3:isp0:0:5:2): READ TOC/PMA/ATIP {MMC
Proposed}
. CDB: 43 40 0 0 0 0 0 0 4 0
May 7 20:53:10 p100 /kernel: (cd3:isp0:0:5:2): ILLEGAL REQUEST asc:20,0
May 7 20:53:10 p100 /kernel: (cd3:isp0:0:5:2): Invalid command operation
code
can with this firmware rev be fixed by switching to SCSI-2 mode. The
driver is now happy because the READ TOC cmd is no longer VU but adheres to
the SCSI2 standard.
I can still get the system to lock up with the default CHANGER_MIN_BUSY_SECONDS
and CHANGER_MAX_BUSY_SECONDS.
A kernel built with
# Pioneer cdloader
options CHANGER_MIN_BUSY_SECONDS=5
options CHANGER_MAX_BUSY_SECONDS=15
works fine, no lockups. Apparantly the defaults are too low for the Pioneer.
All of the above was tested on a Qlogic 1040 board (isp driver).
The only mystery left is that I can't get it to work using the ncr
driver on a ncr810 board:
May 7 23:35:07 p100 savecore: no core dump
May 7 23:35:28 p100 /kernel: ncr1: timeout nccb=0xc0789200 (skip)
May 7 23:35:28 p100 /kernel: (cd1:ncr1:0:5:0): got CAM status 0x4b
May 7 23:35:28 p100 /kernel: (cd1:ncr1:0:5:0): fatal error, failed to
attach to device
May 7 23:35:28 p100 /kernel: (cd1:ncr1:0:5:0): lost device
May 7 23:35:28 p100 /kernel: (cd1:ncr1:0:5:0): removing device entry
May 7 23:35:50 p100 /kernel: ncr1: timeout nccb=0xc0788e00 (skip)
May 7 23:36:12 p100 /kernel: ncr1: timeout nccb=0xc0788e00 (skip)
May 7 23:36:12 p100 /kernel: (cd2:ncr1:0:5:1): got CAM status 0x4b
May 7 23:36:12 p100 /kernel: (cd2:ncr1:0:5:1): fatal error, failed to
attach to device
etc. If anybody has a clue why the ncr is so much more obnoxious...
