Hi guys, I''m getting this kernel oops when using openSuSE 10.1 XEN kernel on dom0. When this happens, linux load average starts incrising dramatically and after some minutes, any application that need access to a file starts to hang. This seems to happen when there is some amount of network traffic (this machine is a samba file server). For now, I have no virtual machines initialized. When I''m using a normal kernel withou xen, there is no problems. I''m using xfs file systems on top of LVM on top of software RAID 5. Any ideas? Thanks in advance. Here goes the oops: Aug 31 08:15:31 mariscal kernel: Oops: 0000 [#1] Aug 31 08:15:31 mariscal kernel: SMP Aug 31 08:15:31 mariscal kernel: last sysfs file: /devices/pci0000:00/0000:00:07 .3/i2c-0/0-0028/temp3_type Aug 31 08:15:31 mariscal kernel: Modules linked in: nfsd lockd nfs_acl sunrpc w8 3781d w83627hf hwmon_vid hwmon i2c_isa button battery ac xfs_quota ext3 jbd loop amd_k7_agp agpgart hw_random i2c_amd756 i2c_core e1000 parport_pc parport ohci_ hcd e100 usbcore mii ide_cd cdrom xfs exportfs dm_snapshot dm_mod raid0 raid1 ra id5 xor fan thermal processor sg aic79xx scsi_transport_spi amd74xx sd_mod scsi_ mod ide_disk ide_core Aug 31 08:15:31 mariscal kernel: CPU: 0 Aug 31 08:15:31 mariscal kernel: EIP: 0061:[<f4a07820>] Tainted: G U V LI Aug 31 08:15:31 mariscal kernel: EFLAGS: 00210246 (2.6.16.21-0.13-xen #1) Aug 31 08:15:31 mariscal kernel: EIP is at xfs_bmbt_delete+0xb20/0x11e0 [xfs] Aug 31 08:15:31 mariscal kernel: eax: ef2eda64 ebx: 00000c00 ecx: 00000001 edx: eff2c000 Aug 31 08:15:31 mariscal kernel: esi: 001e0000 edi: ef2eda64 ebp: eff2c000 esp: eda3b9c4 Aug 31 08:15:31 mariscal kernel: ds: 007b es: 007b ss: 0069 Aug 31 08:15:31 mariscal kernel: Process smbd (pid: 4376, threadinfo=eda3a000 ta sk=c0acccb0) Aug 31 08:15:31 mariscal kernel: Stack: <0>f4a09076 edda59ec f3c3f400 ed7ca500 00000019 00000000 00000001 00000000 Aug 31 08:15:31 mariscal kernel: f4a21607 ed7ca500 00000000 eda3ba50 0000 0003 ed971800 c0fc8a20 eda3bbec Aug 31 08:15:31 mariscal kernel: 00000001 ef2eda64 02162db7 00000002 0300 0001 00020c40 00000009 eff2c000 Aug 31 08:15:31 mariscal kernel: Call Trace: Aug 31 08:15:32 mariscal kernel: [<f4a09076>] xfs_btree_check_sblock+0x96/0xf0 [xfs] Aug 31 08:15:32 mariscal kernel: [<f4a21607>] xfs_inobt_lookup+0x1a7/0x4a0 [xfs ] Aug 31 08:15:32 mariscal kernel: [<f4a1fdee>] xfs_dialloc+0xfee/0x1520 [xfs] Aug 31 08:15:32 mariscal kernel: [<c0107b7b>] monotonic_clock+0x3b/0x80 Aug 31 08:15:32 mariscal kernel: [<c02b4222>] tcp_v4_do_rcv+0xd2/0x340 Aug 31 08:15:32 mariscal kernel: [<c0116acd>] try_to_wake_up+0x8d/0x380 Aug 31 08:15:32 mariscal kernel: [<c02ac6e0>] tcp_data_queue+0x430/0xbf0 Aug 31 08:15:32 mariscal kernel: [<c0296f54>] ip_route_input+0x44/0xda0 Aug 31 08:15:32 mariscal kernel: [<c02b6a9f>] tcp_v4_rcv+0x8cf/0xa60 Aug 31 08:15:32 mariscal kernel: [<c010a7ee>] dma_map_single+0xee/0x150 Aug 31 08:15:32 mariscal kernel: [<f4bfaddc>] e1000_xmit_frame+0x82c/0xdf0 [e10 00] Aug 31 08:15:32 mariscal kernel: [<f4a279a1>] xfs_ialloc+0x61/0x530 [xfs] Aug 31 08:15:32 mariscal kernel: [<f4c63551>] xfs_trans_dqresv+0x121/0x460 [xfs _quota] Aug 31 08:15:32 mariscal kernel: [<f4a3c4c5>] xfs_dir_ialloc+0x85/0x2e0 [xfs] Aug 31 08:15:32 mariscal kernel: [<f4c638fe>] xfs_trans_reserve_quota_bydquots+ 0x6e/0x100 [xfs_quota] Aug 31 08:15:32 mariscal kernel: [<f4a43de6>] xfs_create+0x3b6/0x710 [xfs] Aug 31 08:15:32 mariscal kernel: [<f4a4dc27>] linvfs_mknod+0x217/0x430 [xfs] Aug 31 08:15:32 mariscal kernel: [<f4a0ada4>] xfs_da_do_buf+0x894/0x970 [xfs] Aug 31 08:15:32 mariscal kernel: [<c017f598>] __d_lookup+0x88/0x110 Aug 31 08:15:32 mariscal kernel: [<c017f598>] __d_lookup+0x88/0x110 Aug 31 08:15:32 mariscal kernel: [<f4a3a818>] xfs_trans_unlocked_item+0x38/0x60 [xfs] Aug 31 08:15:32 mariscal kernel: [<f4a4070f>] xfs_access+0x3f/0x50 [xfs] Aug 31 08:15:32 mariscal kernel: [<f4a4d730>] linvfs_permission+0x0/0x20 [xfs] Aug 31 08:15:32 mariscal kernel: [<f4a4d73f>] linvfs_permission+0xf/0x20 [xfs] Aug 31 08:15:32 mariscal kernel: [<c017540c>] permission+0x5c/0xd0 Aug 31 08:15:32 mariscal kernel: [<f4a4e4b0>] linvfs_lookup+0x0/0xb0 [xfs] Aug 31 08:15:32 mariscal kernel: [<c0176a97>] __link_path_walk+0x77/0xea0 Aug 31 08:15:32 mariscal kernel: [<c01774ba>] __link_path_walk+0xa9a/0xea0 Aug 31 08:15:32 mariscal kernel: [<c01840e4>] mntput_no_expire+0x24/0xb0 Aug 31 08:15:32 mariscal kernel: [<c0177931>] link_path_walk+0x71/0xf0 Aug 31 08:15:32 mariscal kernel: [<c0175ab7>] vfs_create+0xc7/0x140 Aug 31 08:15:32 mariscal kernel: [<c0178fc6>] open_namei+0x5d6/0x670 Aug 31 08:15:32 mariscal kernel: [<c016553e>] do_filp_open+0x2e/0x60 Aug 31 08:15:32 mariscal kernel: [<c0165210>] get_unused_fd+0x50/0xb0 Aug 31 08:15:32 mariscal kernel: [<c01655ba>] do_sys_open+0x4a/0xe0 Aug 31 08:15:32 mariscal kernel: [<c016568c>] sys_open+0x1c/0x20 Aug 31 08:15:32 mariscal kernel: [<c0104f25>] syscall_call+0x7/0xb Aug 31 08:15:32 mariscal kernel: Code: 00 8b 45 04 66 83 fa 01 19 d2 83 e2 fc 8b 84 02 ac 01 00 00 8d 1c c5 00 00 00 00 8b 44 24 48 c1 e0 03 89 c1 c1 e9 02 89 4 c 24 18 <f3> a5 89 c1 83 e1 03 74 02 f3 a4 8b bc 24 8c 00 00 00 8b 4c 24 __________________________________________ Vandeir Eduardo (CCNA, LPIC-2, MCSA 2003 Server) Laboratório de Computação e Informática (LCI) -
