http://bugzilla.kernel.org/show_bug.cgi?id=15362 Summary: MPT Fusion SCSI drives no longer appear - suspect PCI bus scan bug Product: IO/Storage Version: 2.5 Kernel Version: 2.6.30-1, 2.6.30-2, 2.6.32-trunk Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: SCSI AssignedTo: linux-scsi@xxxxxxxxxxxxxxx ReportedBy: pegasus@xxxxxxxxxxxxxxxx Regression: Yes Created an attachment (id=25130) --> (http://bugzilla.kernel.org/attachment.cgi?id=25130) 2.6.26 dmesg Since upgrading to the 2.6.30 kernel on an AMD64 platform, drives attached to my LSI/MPT SCSI controller are no longer visible. If I boot using the 2.6.26-2 kernel, it works fine. The SCSI controller doesn't even show up in lspci in kernel versions above 2.6.26. (I do have the controller's BIOS disabled however, but I understand that doesn't matter since the kernel will poll it anyway, as 2.6.26 does. I tested with the controller's BIOS enabled too and it doesn't make a difference.) This has already been submitted to Debian as bug #543308, but evidence points to a bug in the kernel PCI bus scanning code, since the following PCI devices show up on 2.6.26-2 but not 2.6.30-1 and up: 0001:40:01.0 0604: 1022:7450 (rev 12) 0001:40:01.1 0800: 1022:7451 (rev 01) 0001:40:02.0 0604: 1022:7450 (rev 12) 0001:40:02.1 0800: 1022:7451 (rev 01) 0001:61:06.0 0100: 1000:0030 (rev 07) 0001:61:06.1 0100: 1000:0030 (rev 07) 0002:80:00.0 0580: 10de:005e (rev a3) 0002:80:01.0 0580: 10de:00d3 (rev a3) -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. -- 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
