James hi.
Please add this patch for 2.6.33-rc:
http://marc.info/?l=linux-scsi&m=126335810027706&w=2
Titled:
[PATCH 1/1] iscsi_tcp regression: remove bogus warn on in write path
It is a bug introduced in this Kernel. It causes an annoying useless WARN_ON
on ever iscsi login, (and scares the users ;))
Thanks
Boaz
