Distribution: Gentoo Hardware Environment: Dell Inspiron 8000, PIII 900mhz, 256 ram, internal cd-rw, module dvd/floppy, external TDK IndiDVD-RW Problem Description: When disconnect, and reconnecting my external DVD-RW drive I noticed that the drive is not recognized. I've tried this with several different kernel configurations, and kernels versions = 2.6.8.1, 2.6.8, 2.6.7, 2.6.6 If I try to unload the sr_mod module, rmmod just hangs. Sbp2 and all firewire support is currently compiled into my kernel, but I had tried it as a module and has the same behavior (hanging on rmmod). I am able to unload the sr_mod module before I disconnect the drive, in this case reconnecting the drive works like normal. I'm currently at work, when I get home I can attach my kernel config, and proc information. Here is my dmesg output for now: **After plugging in drive the first time** ohci1394: fw-host0: SelfID received, but NodeID invalid (probably new bus reset occurred): 0000FFC0 ieee1394: Node changed: 0-00:1023 -> 0-01:1023 ieee1394: Node resumed: ID:BUS[0-01:1023] GUID[0010100345c4bd87] ieee1394: The root node is not cycle master capable; selecting a new root node and resetting... ieee1394: Node changed: 0-01:1023 -> 0-00:1023 ieee1394: Node changed: 0-00:1023 -> 0-01:1023 scsi0 : SCSI emulation for IEEE-1394 SBP-2 Devices ieee1394: sbp2: Logged into SBP-2 device ieee1394: Node 0-00:1023: Max speed [S400] - Max payload [2048] Vendor: TDK Model: DVDRW840G Rev: 1.03 Type: CD-ROM ANSI SCSI revision: 02 Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 5 sr0: scsi3-mmc drive: 62x/62x writer cd/rw xa/form2 cdda tray Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0 ***After disconnecting Drive*** ieee1394: Node changed: 0-01:1023 -> 0-00:1023 ieee1394: Node suspended: ID:BUS[0-00:1023] GUID[0010100345c4bd87] ***After reconnecting Drive*** ohci1394: fw-host0: SelfID received, but NodeID invalid (probably new bus reset occurred): 0000FFC0 Steps to reproduce: Connect External TDK Drive, Disconnect, Then reconnect.

Is this issue still present in kernel 2.6.19?
These bugs have been fixed, to the best of my knowledge. The most often encountered ones in Linux 2.6.14, some rarer ones in subsequent releases.
(Shannon, please reopen the bug in the highly unlikely case that the problem is still there.)
