I'm forwarding a message I sent to linux1394 developers, but we were
unfortunately unable to find a solution.
This is in a new SONY VAIO laptop, and I am having problems with the IRQ
routing in the machine. For several devices, I get errors about "No IRQ
known for interrupt pin ...", both while booting, and when I try to
activate this ohci1394 module. I have tried 2.4.2, 2.4.3, 2.4.9 and
2.4.10, with different PCI irq settings, as well as turning ACPI on and
off. The only suggestion I got from the linux1394 folks was to make
sure Plug & Play was off in the bios, which I have also tested, and it
didn't help. And supplying "pci=bioirq" into lilo doesn't seem to do
anything useful. It just gets rid of the annoying "Please try using
pci=biosirq" messages. I have a guess, being a very new laptop, that
the problem here is coming from it being a ACPI based system (APM
doesn't even return anything on this system, so I'm pretty sure it's all
ACPI).
If anyone has any suggestions on how to get this machine up and running,
that would be wonderful.
Forwarded below is another message detailing the problem.
Attached to this e-mail are the files:
dmesg.out - output from dmesg
lspci.out - output from lspci -vvvxx
dump_pirq.out - output from the pcmcia-cs perl script, pirq.out
Thanks for your time!

Subject: TI 8021 OHCI Firewire card not being detected as OHCI1394
Date: 26 Sep 2001 18:41:51 -0400
Hello, I am trying to setup a VAIO GR series (PCG-GR100K) laptop with
Firewire. I am familiar with the driver, having used it on an older
VAIO (though with a cardbus PCI card, since that laptop had the
proprietary Sony chip.
Here is output taken from lspci -v:
02:02.0 FireWire (IEEE 1394): Texas Instruments: Unknown device 8021
(rev 02) (prog-if 10 [OHCI])
Here are some specs. lspci -v
Subsystem: Sony Corporation: Unknown device 80e7
Flags: bus master, medium devsel, latency 64
Memory at d0205000 (32-bit, non-prefetchable) [size=2K]
Memory at d0200000 (32-bit, non-prefetchable) [size=16K]
Capabilities: [44] Power Management version 2
In windows, the card is detected and works properly, and reported as a
Texas Instruments OHCI compliant card.
I am using a 2.4.3 kernel, and have applied the patch available from the
ohci1394 website.
When I try to modprobe ohci1394, I get the following messages (kernel
debugging messages turned on):
Sep 26 18:28:17 localhost kernel: ieee1394: registered ohci1394 driver,

Sep 26 18:28:17 localhost kernel: ieee1394: detected 0 ohci1394 adapters
It obviously seems that the problem here is the PCI subsystem, since it
cannot find a suitable IRQ for device 02:02, the Firewire card. This
causes ohci1394 to not find the card, and currently has me rather
flustered.
Any ideas?? This laptop is being used as a tele-op unit to control a
robot (video coming in over firewire, and commands being sent to robot
via 802.11b network). I would just use my old cardbus PCMCIA card, but
I need a slot free to keep the 802.11b card in use.
Thanks!
