[drop hostname part of above IPv6-only address if you want to mail me via
IPv4, or better, drop my address entirely and I'll read the list archives]
Hello hello hello.
I wrote earlier that my Firewire/USB external drive was only found after
boot followed by detach/reattach with the latest (recent) firewire codes,
and an unneeded patch to detach the CAM layer at detach.
Well, I've moved to a different machine, using the same cards, to allow me
to panic and poweroff to juggle hardware without inconveniencing other
long-running programs. This machine had only a 4.5-RC kernel, now 4.9PRE,
an unknown userland from around the same time, and I'm trying to use the
latest kernel modules. None of my patch hacks have been applied.
I wrote that the latest firewire/sbp codes failed to find an attached
drive at boot, when loaded from loader.conf. This may still be true, I'm
going to check Real Soon Now. Yes, it's true. Details follow.
However, if *after* boot I kldload sbp/firewire with the drive attached, it
appears to detect the drive fine and make it available for mounting, as
desired. No need to detach/reattach the cable.
Here is part of the dmesg at boot with auto-load by loader.conf:

It never goes any further than this, until I physically detach and re-attach
the cable. Then, with a new boot, auto-loaded sbp/firewire kernel modules:

Now I've turned my attention to a second card, which had given me problems
before. It's a combination USB2/Firewire card, with a VIA6306 chip (mentioned
a few times in the firewire source files).
A side note, this combination card is a source of problems for me. It
appears that I can successfully load USB modules with it (hacked, as
there seems to be an overcurrent problem), or perhaps firewire modules,
but as soon as I try to load the other functionality, the machine hangs
(on my development machine I can get into the debugger and see it's in a
doreti or doreti_foo) -- likewise at booting that never gets very far when
auto-loaded, most of the time. I have sometimes had some success getting
into NetBSD or FreeBSD-current, but at least NetBSD wedges solid soon after.
The combi-card often does not even see the EUI of the device. Instead,
it spits out:
firewire0: 2 nodes, maxhop <= 1, cable IRM = 1 (me)
fwohci0: fw_set_bus_manager: 1->1 (loop=0)
firewire0: bus manager 1 (me)

fwohci0: maxdesc: 2

node0: resp=60 addr=0x400
fw_xfer_free FWXF_START
bus_explore done
sbp_post_explore (sbp_cold=0)
probe failed for 1 node
Then nothing happens at any bus event. This is with the modules loaded
after boot by hand.
However, this could just be a hardware problem, on this ten-year-old PC.
For when I moved the card to a different slot, and/or removed/exchanged
the ethernet card, and/or removed the sound card, now it does find the
attached drive, although it still needs a physical detach/attach after
boot to give me the drive as da0.
I haven't yet loaded the usb modules with the functioning firewire, to
see if it still wedges the machine. Maybe later.
Thanks,
Barry Bouwsma
