... at least for PPC targets. There was a set of patches applied for the 2.4.21-rc2 kernel (some seem _very_ strange, maybe endianness issues...) that makes sbp2 fail to recognize my external firewire drives. The only way I have for now to make things work is to come back to the 2.4.21-rc1 version, which work correctly for my Mac and my PC (VIA Chipset & Firewire chip). On the Mac (Ibook), I can see my disks in /proc/bus/ieee1394/devices:

but not in /proc/scsi/scsi Here's the output of /proc/scsi/sbp2/1 (with the working driver): IEEE-1394 SBP-2 protocol driver (host: ohci1394) $Rev: 878 $ James Goodwin <jamesg@filanet.com> SBP-2 module load options: - Max speed supported: S400 - Max sectors per I/O supported: 255 - Max outstanding commands supported: 64 - Max outstanding commands per lun supported: 1 - Serialized I/O (debug): no - Exclusive login: yes
I may do more tests to localize the bug, if I only knew which ones I should do...
