When I did a modprobe -r ib_ipoib, I got the following oops when the SA's send_handler is called on it's deregistering it's MAD client with pending MADs.
I first bringup and configure IPoIB: /sbin/modprobe ib_ipoib /sbin/ifconfig ib0 192.168.0.20 I then do: ping -b 192.168.0.255 and ctl-C before it cycles around the list a second time and then: /sbin/modprobe -r ib_ipoib Segmentation fault /var/log/messages showed: Nov 2 10:54:17 hpc-1 kernel: Unable to handle kernel paging request at virtual address f8a50407 Nov 2 10:54:17 hpc-1 kernel: printing eip: Nov 2 10:54:17 hpc-1 kernel: f8a50407 Nov 2 10:54:17 hpc-1 kernel: *pde = 019a5067 Nov 2 10:54:17 hpc-1 kernel: *pte = 00000000 Nov 2 10:54:17 hpc-1 kernel: Oops: 0000 [#1] Nov 2 10:54:17 hpc-1 kernel: SMP Nov 2 10:54:17 hpc-1 kernel: Modules linked in: ib_sa ib_mad ib_services ib_mthca ib_core loop autofs e1000 ohci1394 ieee1394 parport_pc parport usbcore Nov 2 10:54:17 hpc-1 kernel: CPU: 0 Nov 2 10:54:17 hpc-1 kernel: EIP: 0060:[<f8a50407>] Not tainted VLI Nov 2 10:54:17 hpc-1 kernel: EFLAGS: 00010246 (2.6.9) Nov 2 10:54:17 hpc-1 kernel: EIP is at 0xf8a50407 Nov 2 10:54:17 hpc-1 kernel: eax: e2f05280 ebx: 00000286 ecx: 00000000 edx: fffffffb Nov 2 10:54:17 hpc-1 kernel: esi: c6ba3340 edi: c6ba3348 ebp: fffffffb esp: e6eebdfc Nov 2 10:54:17 hpc-1 kernel: ds: 007b es: 007b ss: 0068 Nov 2 10:54:17 hpc-1 kernel: Process modprobe (pid: 12680, threadinfo=e6eea000 task=f5f30230) Nov 2 10:54:17 hpc-1 kernel: Stack: f8a217d8 fffffffb 00000000 e2f05280 e6eebe60 c02a1e5e 00000000 f5f30230 Nov 2 10:54:17 hpc-1 kernel: c0117d96 00000000 00000000 00000003 c170b060 c6ff3a70 c6ff3830 c011685a Nov 2 10:54:17 hpc-1 kernel: f5f30230 e74b5800 f5f30230 00000000 e6eebe98 c02a1a92 c6ff3830 c170e4d0 Nov 2 10:54:17 hpc-1 kernel: Call Trace: Nov 2 10:54:17 hpc-1 kernel: [<f8a217d8>] ib_sa_mcmember_rec_callback+0x5a/0x7f [ib_sa] Nov 2 10:54:17 hpc-1 kernel: [<c02a1e5e>] wait_for_completion+0xc4/0xcc Nov 2 10:54:17 hpc-1 kernel: [<c0117d96>] default_wake_function+0x0/0x12 Nov 2 10:54:17 hpc-1 kernel: [<c011685a>] finish_task_switch+0x3a/0x83 Nov 2 10:54:17 hpc-1 kernel: [<c02a1a92>] schedule+0x326/0x62e Nov 2 10:54:17 hpc-1 kernel: [<f8a21a24>] send_handler+0xaa/0xbc [ib_sa] Nov 2 10:54:17 hpc-1 kernel: [<f89e8642>] cancel_mads+0xe5/0x127 [ib_mad] Nov 2 10:54:17 hpc-1 kernel: [<f89e737a>] ib_unregister_mad_agent+0x16/0x135 [ib_mad] Nov 2 10:54:17 hpc-1 kernel: [<c0117d96>] default_wake_function+0x0/0x12 Nov 2 10:54:17 hpc-1 kernel: [<c0117d96>] default_wake_function+0x0/0x12 Nov 2 10:54:17 hpc-1 kernel: [<f89f2928>] ib_get_client_data+0x42/0x4e [ib_core] Nov 2 10:54:17 hpc-1 kernel: [<f8a21d87>] ib_sa_remove_one+0x44/0x7d [ib_sa] Nov 2 10:54:17 hpc-1 kernel: [<f89f28e1>] ib_unregister_client+0xee/0xf3 [ib_core] Nov 2 10:54:17 hpc-1 kernel: [<c0130ecb>] try_stop_module+0x37/0x3b Nov 2 10:54:17 hpc-1 kernel: [<c0133941>] __try_stop_module+0x0/0x41 Nov 2 10:54:17 hpc-1 kernel: [<f8a21dcf>] ib_sa_cleanup+0xf/0x13 [ib_sa] Nov 2 10:54:17 hpc-1 kernel: [<c01310c1>] sys_delete_module+0x16d/0x19b Nov 2 10:54:17 hpc-1 kernel: [<c01474de>] sys_munmap+0x51/0x76 Nov 2 10:54:17 hpc-1 kernel: [<c0105cf5>] sysenter_past_esp+0x52/0x71 Nov 2 10:54:17 hpc-1 kernel: Code: Bad EIP value. -- Hal _______________________________________________ openib-general mailing list [EMAIL PROTECTED] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
