https://bugzilla.kernel.org/show_bug.cgi?id=71231 Bug ID: 71231 Summary: System unresponsable after a lot of LUNs have been added to the system Product: IO/Storage Version: 2.5 Kernel Version: 3.10.32 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: SCSI Assignee: linux-scsi@xxxxxxxxxxxxxxx Reporter: alexandernaumann@xxxxxx Regression: No Created attachment 127581 --> https://bugzilla.kernel.org/attachment.cgi?id=127581&action=edit Kernel config This Kernel crash is reproducable on my system. Right now I could get it with 3.10.25 and 3.10.32. I works fine with 3.1. The system (Dell R910, nut it also happens with other servers) has a QLogic FC-HBA (qla2xxx driver). After connection about 30 LUNs the system is working fine, but if I increase the amount of FC-LUNs to for example 40 the system hangs afetr some seconds. Maybe this bug has been already fixed by Suse: http://kernel.suse.com/cgit/kernel-source/tree/patches.fixes/mm-resched-to-avoid-rcu-stall-during-boot-large-machines.patch?h=SLE11-SP3&id=6780159bba20e9f99dd5ac8a4e18f98f9c93adf7 If it is the case I think this patch should be put into current kernel lines. -- 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
