is this only on this particular system, or on multiple ppc64 systems? My mistake, by add "xmon=off" to yaboot.conf, I can disable xmon. Then everything goes fine. Hi Neil I've finished the test. Netdump works fine on ppc64. Thanks ChaoYe cool, thanks! |
Description of problem: I setup netdump service. When triggered a crash, it didn't start dump vmcore. I got these from console: =================================================== INIT: version 2.85 reloading [...network console startup...] SysRq : Crashing the kernel by request cpu 0x2: Vector: 300 (Data Access) at [c00000002964f920] pc: c0000000001d047c: .sysrq_handle_crash+0x4/0xc lr: c0000000001d08d8: .__handle_sysrq+0xb8/0x18c sp: c00000002964fba0 msr: 8000000000001032 dar: 0 dsisr: 42000000 current = 0xc00000002f46c5c0 paca = 0xc000000000409800 pid = 3812, comm = bash enter ? for help 2:mon> Version-Release number of selected component (if applicable): kernel-2.6.9-92.EL.ppc64 netdump-0.7.16-15.ppc How reproducible: 100% Steps to Reproduce: 1.Get RHEL4-U9-re20101130.0 installed 2.Setup netdump service 3.Trigger a crash Actual results: Drop Expected results: Additional info: I also tested RHEL4-U8, got same output from console.
