IEEE1394-harddisk-2.6.10 - not working


Hi!

I have read this thread about ieee1394 problem and tried the solution. It didn't work for me.

Let me provide some information.

Firewire card : VIA VT6306 Chipset
Kernel: 2.6.10
Firewire and SCSI emulation compile into the kernel.
External Harddisk: HFSPLUS format.

lspci -vv snipet for my firewire card:
Code:
00:08.0 FireWire (IEEE 1394): VIA Technologies, Inc.: Unknown device 2044 (rev 46) (prog-if 10 [OHCI])
	Subsystem: Unknown device 00ff:8a01
	Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
	Status: Cap+ 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR+
	Latency: 32 (8000ns max), cache line size 08
	Interrupt: pin A routed to IRQ 11
	Region 0: Memory at a0000000 (32-bit, non-prefetchable) [size=2K]
	Region 1: I/O ports at b800 [size=128]
	Capabilities: [50] Power Management version 2
		Flags: PMEClk- DSI- D1- D2+ AuxCurrent=0mA PME(D0-,D1-,D2+,D3hot+,D3cold+)
		Status: D0 PME-Enable- DSel=0 DScale=0 PME-
History of problem: It was working in 2.6.7 then I upgraded the kernel to 2.6.10 which requires udev and other packages to be upgraded. And that is the end of it.

Search LQ and found thread link above. And did the mknod thing. /dev/raw1394 appears in my /dev but that is all. I use to have /dev/sda*.

Do I need to make more nodes for that?

How do I check /sys to know that the kernel have engage my firewire harddrive?

Thanks in advance.

Hi,

Do you have SCSI disk compiled into the kernel (edit - or as a module)? Not sure if it's relevant, but I think it's required for the SCSI emulation to access my usb-storage devices.

The other thing, Udev doesn't automatically create devices files for all devices, because their drivers don't register with SysFS properly (yet...) Maybe you should reboot into your old kernel, make a note of what devices are created and manually create them with the 2.6.10 kernel.

Once your device is created, and if SysFS has registered the device, try
Code:
udevinfo -q path -n /dev/sda*
to find out where your device is in the SysFS hierarchy. Replace the '*' ofcourse with your own number...

Then try
Code:
udevinfo -a -p /results/of/above/command/in/here
e.g.
udevinfo -a -p /block/sda/sda1
to see what SysFS knows about it...

Hope this helps a bit...
