http://bugzilla.kernel.org/show_bug.cgi?id=10486 Summary: kernel 2.6.25 4G FC arrays don't work properly with qla2xxx driver Product: SCSI Drivers Version: 2.5 KernelVersion: 2.6.25 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: blocking Priority: P1 Component: QLOGIC QLA2XXX AssignedTo: scsi_drivers-qla2xxx@xxxxxxxxxxxxxxxxxxxx ReportedBy: andrej.filipcic@xxxxxx Latest working kernel version: 2.6.23 Earliest failing kernel version: 2.6.24 Distribution: gentoo Hardware Environment: opteron Software Environment: x86_64 Problem Description: With 2.6.24 and 25 there are troubles with qla2xxx module. 4G FC arrays (Infortrend) are not working properly, while 2G FC are OK.

I am not sure whether this is a regression in the driver or something else. The controller is QLogic QLE220 - PCI-Express to 4Gb FC, Single Channel ISP5432: PCIe (2.5Gb/s x4) and firmware version is 4.02.02 (from sys-block/qla-fc-firmware-20071207) On qlogic site there is a newer firmware (4.03.02), although I doubt the firmware would be the cause of the problems. To be honest, I have not checked 2.6.25 release but rather rc8, however there are no qla2xxx related patches since then. Steps to reproduce: boot 2.6.24 or 25, run vgscan -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
