From mboxrd@z Thu Jan 1 00:00:00 1970 Message-ID: <3A0E57BA.44CFBDE7@emory.edu> Date: Sun, 12 Nov 2000 00:41:30 -0800 From: Andreas H Meier MIME-Version: 1.0 To: linuxppc-dev@lists.linuxppc.org Subject: IEEE1394 hard drive woes on pismo Content-Type: text/plain; charset=us-ascii Sender: owner-linuxppc-dev@lists.linuxppc.org List-Id: I am looking for some advice with ieee1394 on a pismo. I am trying to talk to a 30GB Fantom FireWire hard drive from linux and have so far been unsuccessful. I can get the firewire port up and running, and plugging in the harddrive is registered by /proc/ohci1394 (see below). Any attempt to access the harddrive (testlibraw, gscanbus) results in unrecoverable system freeze (screen stays, keyboard no longer working. Has anybody been able to get a firewire harddrive to work on a pismo? If yes, let me know. Can I use the linux1394 stuff from sourceforge or is there another tree specifically for ppc? Thanks, here is my system info and the relevant file printouts: ####System info ############# Linux kernel 2.2.18pre17-ben1 on pismo 500 patched with linux1394 patch for 2.2 kernel (http://linux1394.sourceforge.net) relevant modules loaded: sbp2_1394 raw1394 ohci1394 ieee1394 ####/dmesg output, harddrive plugged in ############# /SNIP ieee1394: registered ohci1394 driver, initializing now ohci1394: looking for Ohci1394 cards PCI: Enabling bus mastering for device 00:70 ohci1394_0: remapped memory spaces reg 0xe4874000 ohci1394_0: allocated interrupt 40 ohci1394_0: soft reset finished ohci1394_0: max packet size = 2048 bytes ohci1394_0: 4 iso receive contexts available ohci1394_0: 4 iso transmit contexts available ohci1394_0: Receive DMA ctx=0 initialized ohci1394_0: Receive DMA ctx=1 initialized ohci1394_0: AT dma ctx=0 initialized ohci1394_0: AT dma ctx=1 initialized ohci1394_0: Receive DMA ctx=2 initialized ohci1394_0: resetting bus on request ieee1394: detected 1 ohci1394 adapter ohci1394_0: irq_handler timeout event=0x00020000 ohci1394_0: SelfID process finished (phyid 0, not root) ohci1394_0: selfid packet 0x807f8c92 rcvd ieee1394: including selfid 0x807f8c92 ohci1394_0: This node self-id is 0x807f8c92 ohci1394_0: selfid packet 0x817f84d0 rcvd ieee1394: including selfid 0x817f84d0 ohci1394_0: calling self-id complete ieee1394: GUID request sent to node 1 ohci1394_0: phy reg received outside of bus resetsequence raw1394: /dev/raw1394 device initialized SBP-2 storage driver for IEEE-1394 scsi0 : IEEE-1394 SBP-2 storage driver scsi : 1 host. /SNIP ####lspci -vvx output, harddrive plugged in############# /SNIP 00:0e.0 FireWire (IEEE 1394): Apple Computer Inc.: Unknown device 0018 (rev 01) (prog-if 10) Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz+ UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- SERR-
