[Xen-users] Constant kernel oopses involving vfs_stat_fd and vfs_lstat_fd
I am using the Xen version that comes with FC5 (although this has also happened on FC4 and CentOS 4.2 with other versions of Xen), and am having a problem with the kernel constantly oopsing in a similar way. Here is one of them: Mar 24 10:03:14 hydra kernel: <1>Unable to handle kernel NULL pointer dereference at virtual address 0000003c Mar 24 10:03:14 hydra kernel: printing eip: Mar 24 10:03:14 hydra kernel: c0161676 Mar 24 10:03:14 hydra kernel: *pde = ma 39c9c067 pa 332e7067 Mar 24 10:03:14 hydra kernel: *pte = ma 00000000 pa 55555000 Mar 24 10:03:14 hydra kernel: Oops: 0000 [#15] Mar 24 10:03:14 hydra kernel: SMP Mar 24 10:03:14 hydra kernel: Modules linked in: nls_utf8 cifs xt_tcpudp xt_physdev iptable_filter ip_tables x_tables bridge autofs4 hidp l2cap bluetooth ipv6 video button battery ac lp parport_pc parport nvram uhci_hcd ehci_hcd sg e1000 i2c_i801 i2c _core i6300esb e752x_edac edac_mc dm_snapshot dm_zero dm_mirror dm_mod ext3 jbd ata_piix libata sd_mod scsi_mod Mar 24 10:03:14 hydra kernel: CPU: 3 Mar 24 10:03:14 hydra kernel: EIP: 0061:[<c0161676>] Not tainted VLI Mar 24 10:03:14 hydra kernel: EFLAGS: 00010246 (2.6.15-1.2054_FC5xen0 #1) Mar 24 10:03:14 hydra kernel: EIP is at vfs_getattr+0x35/0xa5 Mar 24 10:03:14 hydra kernel: eax: 00000000 ebx: f3e937b8 ecx: f3fea440 edx: c09f82c8 Mar 24 10:03:14 hydra kernel: esi: c09f82c8 edi: ec005f70 ebp: f3fea440 esp: ec005edc Mar 24 10:03:14 hydra kernel: ds: 007b es: 007b ss: 0069 Mar 24 10:03:15 hydra smartd[1893]: smartd received signal 15: Terminated Mar 24 10:03:15 hydra kernel: Process pidof (pid: 9695, threadinfo=ec004000 task=c04a0df0) Mar 24 10:03:15 hydra smartd[1893]: smartd is exiting (exit status 0) Mar 24 10:03:15 hydra kernel: Stack: <0>00000000 ec005efc bfb53f10 ec004000 c0161715 f3fea440 c09f82c8 ec005f70 Mar 24 10:03:15 hydra kernel: c09f82c8 f3fea440 00000000 c02f5603 f1b3c994 00000000 00000001 00000000 Mar 24 10:03:15 hydra kernel: f3fe76b8 000003e4 ec02008c f1b3c994 c02f5613 40000010 00000000 00000000 Mar 24 10:03:15 hydra kernel: Call Trace: Mar 24 10:03:15 hydra kernel: [<c0161715>] vfs_lstat_fd+0x2f/0x42 Mar 24 10:03:15 hydra kernel: [<c02f5603>] _spin_unlock+0x6/0x8 Mar 24 10:03:15 hydra kernel: [<c02f5613>] _spin_lock+0x6/0x8 Mar 24 10:03:15 hydra kernel: [<c0161760>] vfs_lstat+0xf/0x13 Mar 24 10:03:15 hydra kernel: [<c0161774>] sys_lstat64+0x10/0x26 Mar 24 10:03:15 hydra kernel: [<c011323d>] do_page_fault+0x0/0x6a8 Mar 24 10:03:15 hydra kernel: [<c0104b3d>] syscall_call+0x7/0xb Mar 24 10:03:15 hydra kernel: Code: 24 18 8b 7c 24 1c 8b 5e 18 f6 83 a1 01 00 00 02 75 13 56 55 a1 a0 cc 42 c0 ff 90 c4 00 00 00 59 5a 85 c0 75 71 8b 83 b8 00 00 00 <8b> 48 3c 85 c9 74 12 89 7c 24 1c 89 74 24 18 89 6c 24 14 5b 5e These oopses *always* have either "vfs_stat_fd" or "vfs_lstat_fd" at the top of the call trace. Does anyone know why this might be? If it is any help here is the output from lspci so you know what hardware I have (it is a SuperMicro motherboard): 00:00.0 Host bridge: Intel Corporation E7320 Memory Controller Hub (rev 0c) 00:02.0 PCI bridge: Intel Corporation E7525/E7520/E7320 PCI Express Port A (rev 0c) 00:03.0 PCI bridge: Intel Corporation E7525/E7520/E7320 PCI Express Port A1 (rev 0c) 00:1c.0 PCI bridge: Intel Corporation 6300ESB 64-bit PCI-X Bridge (rev 02) 00:1d.0 USB Controller: Intel Corporation 6300ESB USB Universal Host Controller (rev 02) 00:1d.1 USB Controller: Intel Corporation 6300ESB USB Universal Host Controller (rev 02) 00:1d.4 System peripheral: Intel Corporation 6300ESB Watchdog Timer (rev 02) 00:1d.5 PIC: Intel Corporation 6300ESB I/O Advanced Programmable Interrupt Controller (rev 02) 00:1d.7 USB Controller: Intel Corporation 6300ESB USB2 Enhanced Host Controller (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 0a) 00:1f.0 ISA bridge: Intel Corporation 6300ESB LPC Interface Controller (rev 02) 00:1f.2 IDE interface: Intel Corporation 6300ESB SATA Storage Controller (rev 02) 00:1f.3 SMBus: Intel Corporation 6300ESB SMBus Controller (rev 02) 03:03.0 Ethernet controller: Intel Corporation 82541GI/PI Gigabit Ethernet Controller 03:04.0 Ethernet controller: Intel Corporation 82541GI/PI Gigabit Ethernet Controller 04:05.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev 27) Could someone pleeeease help me with this it''s driving me crazy!
