Description Stefan Katletz 2005-01-25 00:02:28 UTC 
Distribution: debian sarge / ubuntu 4.10 / Mandrake 10.1
Hardware Environment: Asus laptop L3 (P4M) & FireWire (IEEE 1394): Ricoh Co Ltd
R5C552 IEEE 1394 Controller & external USB/firewire harddisk (ICY box)
Software Environment: kernel 2.6.8
Problem Description: the scsi emulation for the external hard disk connected via
firewire doesn't work (USB works). With 2.4.18 kernel there was no problem.

Steps to reproduce: Autoloading produces in dmesg:

ieee1394: Error parsing configrom for node 0-00:1023
ieee1394: Node changed: 0-00:1023 -> 0-01:1023
ieee1394: Node added: ID:BUS[0-00:1023]  GUID[0050770e00071002]
ieee1394: unsolicited response packet received - no tlabel match

ieee1394: sbp2: Error logging into SBP-2 device - login timed-out
sbp2: probe of 0050770e00071002-0 failed with error -16

ieee1394: sbp2: Error logging into SBP-2 device - login timed-out
sbp2: probe of 0050770e00071002-0 failed with error -16

with manual insertion I can see the disc in /proc/scsi/scsi but it doesn't work:

modprobe iee1394
modprobe ohci1394
modprobe sbp2
cat /proc/scsi/scsi

Comment 1 Neil Gierman 2005-03-26 21:01:32 UTC 
Same issue here with a few differences.

Gentoo distro.

Kernel 2.6.10-r6 was working just fine however just upgraded to 2.6.11-r4 and
started seeing the same issue as reported above however only on my 250GB
external drive. 100GB external drive still works on IEEE and 250 is now working
on USB 2.0 controller on same machine.

Comment 2 T. B. Mloduchowski 2005-05-08 00:59:41 UTC 
Fails with unsolicited response packets here, on Alpha, too.. But, this time it gets around after couple hundreds lines to SCSI status report.  However, any operation on device is very slow, and results in even move tlabel_match errors... I can't get it to work faster than mere 2MB/s  Kernel 2.6.10 TSB12LV26 firewire card, (PCI32)  Alpha MiataGL (PWS) EV56 600MHz machine.
Comment 3 Stefan Katletz 2005-07-06 09:40:40 UTC 
The Icy Box IB-350UE-BL http://www.icybox.de/ uses the Prolific chipset PL-3507
(ver. C in my case). Updating the firmware from
http://tech.prolific.com.tw/visitor/v_fileBrw.asp?cateId=973849&cateName=USB%2F1394+IDE+Controller+IC
resolved the problem.
