Summary: Scsi modules hang on firewire device reconnect

Description Shannon Field 2004-08-24 10:50:18 UTC 
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**

***After reconnecting Drive***

Steps to reproduce:
Connect External TDK Drive, Disconnect, Then reconnect. Notice upon reconnection
no device nodes were created. Try 'rmmod sr_mod'.

THis is all the system information when the device is properly connected and
recognized:

Is this issue still present in kernel 2.6.19?
Comment 4 Stefan Richter 2006-12-12 14:24:46 UTC 
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.
Comment 5 Stefan Richter 2006-12-12 14:28:32 UTC 
(Shannon, please reopen the bug in the highly unlikely case that the problem is
still there.)
