Ok so I guess working with old versions of open-iscsi is not accepted
here :). So I upgraded to the latest and greatest semi-stable
release, 871. I no longer see the "is not queued" messages and my
login and logout work fine. However this is the only the case if I
don't have my flash device mounted on /dev/sdc. If the flash is
mounted I get this kernel oops:

In addition. Even if I remove the flash drive, when I continually
log in and logout of my remote SCSI device the device nodes keep
incrementing. In the past it would just stay on the same device nodes
unless the scsi device's configuration changed. Ive added a log of
this behavior in the uploads section. The file is incDevNodes.
Can anyone help? Does anyone have any input on this? My build is
working fine and my kernel is being patched. Here are my system stats
again:
1. Kernel: 2.6.22.10
2. Open-Iscsi Version: iscsiadm version 2.0-871
3. Nexsan SCSI device
Thanks,
JD
