I got a Lacie 320g firewire drive for my Sun Blade 100. This got errors
after running for a while on debian/unstable so I ran it for a couple of
weeks on an IMac and saw no errors. Now I have built 2.6.23rc3 with the
new drivers/firewire modules firewire-core, firewire-ohci and firewire-sbp2.
firewire-core loads ok but firewire-ohci gets the oops below. I tried
some traces that suggest the oops actually happens at
dma_sync_single_for_device but don't know if that is reliable.
A kernel with these modules included will not boot, as it cannot find
/dev/hda2 after the oops.
The modules code is in drivers/firewire and .config has:
#
# IEEE 1394 (FireWire) support
#
CONFIG_FIREWIRE=m
CONFIG_FIREWIRE_OHCI=m
CONFIG_FIREWIRE_SBP2=m
