Hi,
The iscsi_sfnet module I compiled against my 2.6.10-xen0 tree loads
fine, but when the iscsid process goes to discover the luns, it sees the
luns but dumps error strings similar to the following:
------------------------
Attached scsi disk sdb at scsi0, channel 0, id 0, lun 0

-----------------------------------------------------
This will happen whenever there is any i/o against an iSCSI lun. Any
ideas? I'm currently working on compiling a standard 2.6.10 kernel and
seeing if this problem recurs.
Do not bother retying it is not xen.
it is a scsi-ml problem.
Basically, if someone returns EH_HANDLED in their
scsi_times_out functions you will hit this.
It is becuase scsi_times_out is running from
a timer, and if you return EH_HANDLED __scsi_done
is called and that will call local_irq_save.
In future versions of the driver we just
removed our scsi_times_out function becuase
it was not buying us very much. Forgot to
report this bug though.
Thanks,
Matt
