http://bugzilla.kernel.org/show_bug.cgi?id=13452 Summary: When log in a iscsi target it's fail and there is a bug scsi related Product: SCSI Drivers Version: 2.5 Kernel Version: 2.6.27.5-xen.hg Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Other AssignedTo: scsi_drivers-other@xxxxxxxxxxxxxxxxxxxx ReportedBy: jrodriguez@xxxxxx Regression: No I'm using a 2.6.27.5-hg Xen kernel. Modules iscsi_tcp and libiscsi are loaded but when I log in a target iscsi syslog says that there is a kernel bug in /var/xen/linux-2.6.27-xen.hg/drivers/scsi/scsi_lib.c:1759. I have download a mainline kernel 2.6.27.5 and the source code differs. 2.6.27.5-xen.hg 1757 struct device *dev = dev_to_nonscsi_dev(shost->shost_gendev.parent); 1759 BUG_ON(!dev); 2.6.27.5 mainline 1634 struct device *dev = shost->shost_gendev.parent; I suposse that the Xen kernel is patched with "[PATCH][REPOST] scsi_lib_dma.c : fix bug w/ dma on virtual fc ports." so i'm not sure if another kernel upper 2.6.27.5 are "bugged?". Thank you.
