Re this problem: I just installed Arjan's test11 kernel and I can still
see only 1 of 3 firewire devices on my system (gscanbus sees all 3 and I
see from log messages that at least part of the code sees more than 1).
But /proc/scsi/scsi only has:
cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: Maxtor Model: 5000XT Rev: 0100
Type: Direct-Access ANSI SCSI revision: 06

I also see these slab errors. Relevant parts of dmesg output are:
