Hi.  Dmesg gives the following when booting 2.6.3-rc2:
ieee1394: Host added: ID:BUS[0-02:1023]  GUID[001106001a250051]

I'm running Fedora Core1 (updated with yum).  I haven't seen any other
problems like this on LKML and 2.6.3-rc1-bk2 works fine.  lsmod shows:
scsi_mod               96056  5 sd_mod,sr_mod,ide_scsi,sbp2,sg
and
ieee1394               67376  3 raw1394,sbp2,ohci1394
and the system doesn't stall on this, but firewire devices are not
present.  

/var/log/messages shows:
