http://bugzilla.kernel.org/show_bug.cgi?id=9734 Summary: I/O error when inserting a second firewire sata disk Product: IO/Storage Version: 2.5 KernelVersion: 2.6.24 rc7 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: SCSI AssignedTo: linux-scsi@xxxxxxxxxxxxxxx ReportedBy: sbu@xxxxxxxxxxxxxxxxxxxxxx Latest working kernel version: 2.6.18-5 (can't test any other kernel between 2.6.18-5 and 2.6.22-3 because aren't in the repo) Earliest failing kernel version: 2.6.22-3 Distribution: debian lenny 32bit AND 64 bit (it happens the same on both) Hardware Environment: ibm x3400 quad core 2GB ram type/number 7976-KBG bios version 1.56 http://www-03.ibm.com/systems/x/tower/x3400/specs.html cpu info: -> http://www.pastebin.org/15078 lspci firewire: -> http://www.pastebin.org/15081 lsmod: -> http://www.pastebin.org/15083 Software Environment: bash Problem Description: We have a 64bit pci double firewire 800 port to which I attach 2 sata hdd (it doesn't matter the brand of the hdd. We tried many) Everything works well until we use only one disk. Connecting a second disk when we are working on the first one (i.e. writing to the first device) causes the interruption of the first job. once happened also a kernel freeze but we can't document and reproduce it right now. Steps to reproduce: We attach a sata disk to the first port of the pci firewire B controller 08:02.0 FireWire (IEEE 1394): Texas Instruments TSB82AA2 IEEE-1394b Link Layer Controller (rev 01) Jan 12 16:19:13 x3400 kernel: ieee1394: Error parsing configrom for node 1-00:1023 Jan 12 16:19:13 x3400 kernel: ieee1394: Node changed: 1-00:1023 -> 1-01:1023 Jan 12 16:19:14 x3400 kernel: ieee1394: Node resumed: ID:BUS[1-00:1023] GUID[0030e002e0454697] Jan 12 16:19:14 x3400 kernel: scsi9 : SBP-2 IEEE-1394 Jan 12 16:19:15 x3400 kernel: ieee1394: sbp2: Logged into SBP-2 device Jan 12 16:19:15 x3400 kernel: ieee1394: Node 1-00:1023: Max speed [S800] - Max payload [4096] Jan 12 16:19:15 x3400 kernel: Vendor: WDC WD16 Model: 00JD-00HBC0 Rev: 08.0 Jan 12 16:19:15 x3400 kernel: Type: Direct-Access-RBC ANSI SCSI revision: 04 Jan 12 16:19:15 x3400 kernel: SCSI device sdc: 312579695 512-byte hdwr sectors (160041 MB) Jan 12 16:19:15 x3400 kernel: sdc: Write Protect is off Jan 12 16:19:15 x3400 kernel: sdc: Mode Sense: 11 00 00 00 Jan 12 16:19:15 x3400 kernel: SCSI device sdc: drive cache: write back Jan 12 16:19:15 x3400 kernel: SCSI device sdc: 312579695 512-byte hdwr sectors (160041 MB) Jan 12 16:19:15 x3400 kernel: sdc: Write Protect is off Jan 12 16:19:15 x3400 kernel: sdc: Mode Sense: 11 00 00 00 Jan 12 16:19:15 x3400 kernel: SCSI device sdc: drive cache: write back Jan 12 16:19:15 x3400 kernel: sdc: unknown partition table Jan 12 16:19:15 x3400 kernel: sd 9:0:0:0: Attached scsi disk sdc now we launch : dd if=/dev/zero of=/dev/sdc everything ok until now now we attach another sata disc to the second port of the pci firewire controller: Jan 12 16:20:09 x3400 kernel: ieee1394: Error parsing configrom for node 1-00:1023 Jan 12 16:20:09 x3400 kernel: ieee1394: Node changed: 1-00:1023 -> 1-01:1023 Jan 12 16:20:09 x3400 kernel: ieee1394: Node changed: 1-01:1023 -> 1-02:1023 Jan 12 16:20:10 x3400 kernel: ieee1394: Reconnected to SBP-2 device Jan 12 16:20:10 x3400 kernel: ieee1394: Node 1-01:1023: Max speed [S800] - Max payload [4096] using 2.6.18-5-686 everything works well dd still works now we disconnect the disk from the second port Jan 12 16:21:13 x3400 kernel: ieee1394: Node changed: 1-01:1023 -> 1-00:1023 Jan 12 16:21:13 x3400 kernel: ieee1394: Node changed: 1-02:1023 -> 1-01:1023 Jan 12 16:21:13 x3400 kernel: ieee1394: Reconnected to SBP-2 device Jan 12 16:21:13 x3400 kernel: ieee1394: Node 1-00:1023: Max speed [S800] - Max payload [4096] everything ok also disconnecting the second device ------------------------------------------------------- now the same issue using 2.6.24-rc7-686: we attach a sata disk to the first port of the pci firewire B controller Jan 12 16:49:45 x3400 kernel: firewire_core: phy config: card 1, new root=ffc1, gap_count=5 Jan 12 16:49:46 x3400 kernel: scsi11 : SBP-2 IEEE-1394 Jan 12 16:49:46 x3400 kernel: firewire_core: created new fw device fw2 (2 config rom retries, S800) Jan 12 16:49:46 x3400 kernel: firewire_sbp2: logged in to fw2.0 LUN 0000 (0 retries) Jan 12 16:49:46 x3400 kernel: scsi 11:0:0:0: Direct-Access-RBC WDC WD16 00JD-00HBC0 08.0 PQ: 0 ANSI: 4 Jan 12 16:49:46 x3400 kernel: sd 11:0:0:0: [sdc] 312579695 512-byte hardware sectors (160041 MB) Jan 12 16:49:46 x3400 kernel: sd 11:0:0:0: [sdc] Write Protect is off Jan 12 16:49:46 x3400 kernel: sd 11:0:0:0: [sdc] Mode Sense: 11 00 00 00 Jan 12 16:49:46 x3400 kernel: sd 11:0:0:0: [sdc] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA Jan 12 16:49:46 x3400 kernel: sd 11:0:0:0: [sdc] 312579695 512-byte hardware sectors (160041 MB) Jan 12 16:49:46 x3400 kernel: sd 11:0:0:0: [sdc] Write Protect is off Jan 12 16:49:46 x3400 kernel: sd 11:0:0:0: [sdc] Mode Sense: 11 00 00 00 Jan 12 16:49:46 x3400 kernel: sd 11:0:0:0: [sdc] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA Jan 12 16:49:46 x3400 kernel: sdc: unknown partition table Jan 12 16:49:46 x3400 kernel: sd 11:0:0:0: [sdc] Attached SCSI disk now we launch : dd if=/dev/zero of=/dev/sdc now we attach another sata disk to the second port of the pci firewire B controller: Jan 12 16:50:49 x3400 kernel: firewire_sbp2: orb reply timed out, rcode=0x11 Jan 12 16:50:49 x3400 kernel: sd 11:0:0:0: [sdc] Result: hostbyte=DID_BUS_BUSY driverbyte=DRIVER_OK,SUGGEST_OK Jan 12 16:50:49 x3400 kernel: end_request: I/O error, dev sdc, sector 2942302 Jan 12 16:50:49 x3400 kernel: printk: 571588 messages suppressed.
