On another machine I increased the kernel messages verbosity, and now it crashes in cca 5% of the runs. Crash details from serial console follow. After the crash, the system is in a state when you cannot login anymore, and running processes do not respond to anything that I tried; but one still gets ping responses. Crash details: Welcome to openSUSE 11.0 (X86-64) - Kernel 2.6.25.5-1.1-default (ttyS0). michelle login: BUG: unable to handle kernel paging request at 0000000000100108 IP: [<ffffffff802bd10b>] __writeback_single_inode+0x346/0x394 PGD 0 Oops: 0002 [1] SMP last sysfs file: /sys/devices/pci0000:00/0000:00:1e.0/0000:06:03.0/class CPU 1 Modules linked in: nfsd auth_rpcgss exportfs nfs lockd nfs_acl lp parport_pc ppdev parport joydev st ide_disk ide_cd_mod ide_core sunrpc iptable_filter ip_tables ip6table_filter ip6_tables x_tables ipv6 af_packet cpufreq_conservative cpufreq_userspace cpufreq_powersave acpi_cpufreq loop dm_mod snd_hda_intel snd_pcm snd_timer snd_page_alloc rtc_cmos snd_hwdep rtc_core rtc_lib i2c_i801 snd iTCO_wdt e1000e ohci1394 sr_mod ieee1394 i2c_core cdrom soundcore sg iTCO_vendor_support button intel_agp sd_mod ehci_hcd uhci_hcd usbcore edd reiserfs fan thermal processor ahci pata_marvell libata scsi_mod dock [last unloaded: parport_pc] Pid: 2374, comm: rpciod/1 Tainted: G N 2.6.25.5-1.1-default #1 RIP: 0010:[<ffffffff802bd10b>] [<ffffffff802bd10b>] __writeback_single_inode+0x346/0x394 RSP: 0018:ffff81007a6d1c90 EFLAGS: 00010246 RAX: 0000000000200200 RBX: 0000000000000000 RCX: ffff810043d15d80 RDX: 0000000000100100 RSI: 0000000000000000 RDI: ffff810043d15e88 RBP: ffff81007a6d1d10 R08: 0000000000000001 R09: 0000000000000000 R10: ffffffff8051ab25 R11: 0000000000000000 R12: ffff810043d15d70 R13: ffff810043d15e80 R14: 0000000000000000 R15: ffff81007a6d1d20 FS: 0000000000000000(0000) GS:ffff81007e36f640(0000) knlGS:0000000000000000 CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b CR2: 0000000000100108 CR3: 0000000000201000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process rpciod/1 (pid: 2374, threadinfo ffff81007a6d0000, task ffff81007a612300) Stack: ffff810005019280 0000000105019280 ffff81007a6d1cd0 ffffffff8022b623 0000000000000001 ffff810079452680 ffff810005019280 ffff810043d15d70 ffff81007a534a00 0000000000000001 ffff81007a4aabe8 ffff810043d15d70 Call Trace: [<ffffffff802bd205>] write_inode_now+0x7d/0xc4 [<ffffffff802b403d>] generic_drop_inode+0x9e/0x169 [<ffffffff802b3191>] iput+0x7c/0x80 [<ffffffff884b827e>] :nfs:nfs_free_unlinkdata+0x18/0x39 [<ffffffff884b845f>] :nfs:nfs_async_unlink_release+0x64/0x68 [<ffffffff883c9971>] :sunrpc:rpc_release_calldata+0x1f/0x29 [<ffffffff883c99f9>] :sunrpc:rpc_put_task+0x7e/0x86 [<ffffffff883ca490>] :sunrpc:__rpc_execute+0x23d/0x246 [<ffffffff883ca537>] :sunrpc:rpc_async_schedule+0x10/0x12 [<ffffffff80246e5c>] run_workqueue+0x8b/0x11a [<ffffffff80246fc8>] worker_thread+0xdd/0xee [<ffffffff8024a22d>] kthread+0x49/0x76 [<ffffffff8020d058>] child_rip+0xa/0x12 DWARF2 unwinder stuck at child_rip+0xa/0x12 Leftover inexact backtrace: [<ffffffff8024a1e4>] ? kthread+0x0/0x76 [<ffffffff8020d04e>] ? child_rip+0x0/0x12 Code: 74 29 48 89 42 08 48 89 10 48 8b 05 e0 f8 34 00 48 89 48 08 49 89 44 24 10 49 c7 44 24 18 d0 c9 60 80 48 89 0d c7 f8 34 00 eb 27 <48> 89 42 08 48 89 10 48 8b 05 c7 f8 34 00 48 89 48 08 49 89 44 RIP [<ffffffff802bd10b>] __writeback_single_inode+0x346/0x394 RSP <ffff81007a6d1c90> CR2: 0000000000100108 ---[ end trace ce6c6a2dc00659a5 ]--- -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
