This host is mainly used as a samba fileserver. The problem has been seen on 2 different machines (both Dell-pe-2600s). The problem is only ever seen when running the SMP kernel in conjunction with samba. We have been experiencing problems since early January when the samba/nfs/io load was increased considerably. Since then a number of 2.4 kernels have been used: 2.4.22.2115nptlsmp (FC1) 2.4.22-1.2199smp (FC1) 2.4.29 (vanilla kernel) 2.6.10-1.741_FC3smp (FC3) 2.6.10-1.766_FC3smp (FC3) All 2.4 kernels produced the same result: full system lock-up, with no messages on the console or the log files. The 2.6.10 kernel is giving an oops which has been seen 3 time in the last 3 days. A very similar one was seen pointing to eip: c01b2d98 on the 2.6.10-1.741 kernel. I have included the kallsyms and System.map relevant to the instruction pointed to by the EIP. I can include the full files if required. printing eip: c01b387c *pde = 2fcdd001 Oops: 0000 [#1] SMP Modules linked in: nfsd exportfs md5 ipv6 parport_pc lp parport autofs4 nfs lockd sunrpc video button battery ac uhci_hcd hw_random e1000 floppy sg dm_snapshot dm_zero dm_mirror ext3 jbd dm_mod mptscsih mptbase sd_mod scsi_mod CPU: 1 EIP: 0060:[] Not tainted VLI EFLAGS: 00010203 (2.6.10-1.766_FC3smp) EIP is at __rb_rotate_left+0x8/0x36 eax: f57be640 ebx: c041e5e4 ecx: f57be640 edx: 00000000 esi: f57be640 edi: f5f39c80 ebp: c041e5e4 esp: efa2eed0 ds: 007b es: 007b ss: 0068 Process smbd (pid: 8536, threadinfo=efa2e000 task=f7612a60) Stack: f5ac1980 c01b3988 f5f39c80 f5f39c80 f5ac1988 00000267 c01965d7 f5ac1980 0000000d efa2ef54 efa2ef61 ffffffea c019668b 00000015 00000000 00000267 c03191e0 efa2ef54 00000000 f599ed80 00000267 c01977df ffffffff 001f0000 Call Trace: [] rb_insert_color+0xa8/0xc1 [] key_user_lookup+0xcf/0xfc [] key_alloc+0x53/0x2b6 [] keyring_alloc+0x1a/0x48 [] alloc_uid_keyring+0x2b/0x7c [] alloc_uid+0xae/0x133 [] set_user+0xb/0x8b [] sys_setresuid+0x11a/0x1b9 [] syscall_call+0x7/0xb Code: 82 04 01 00 00 00 75 ea 41 83 f9 01 76 ed 31 c0 5b c3 57 b9 45 00 00 00 89 c7 31 c0 f3 ab 5f c3 90 90 90 53 89 d3 8b 50 08 89 c1 <8b> 42 0c 85 c0 89 41 08 74 02 89 08 89 4a 0c 8b 01 85 c0 89 02 /proc/kallsyms grepped on c01b3. c01b3024 t newary c01b313c T sys_semget c01b325a t try_atomic_semop c01b336b t update_queue c01b33de t count_semncnt c01b342c t count_semzcnt c01b347a t freeary c01b34f6 t copy_semid_to_user c01b354b t semctl_nolock c01b3731 t semctl_main c01b3ad6 t semctl_down c01b3c39 T sys_semctl c01b3ce9 t lookup_undo c01b3d19 t find_undo root@msh2-c boot]# grep -i c01b3 /boot/System.map-2.6.10-1.766_FC3smp c01b304b T match_int c01b3052 T match_octal c01b305c T match_hex c01b3066 T match_strcpy c01b3098 T match_strdup c01b30c0 t radix_tree_node_alloc c01b3109 T radix_tree_preload c01b317d t radix_tree_extend c01b321c T radix_tree_insert c01b3303 T radix_tree_lookup c01b3349 T radix_tree_tag_set c01b33b8 T radix_tree_tag_clear c01b347a t __lookup c01b3547 T radix_tree_gang_lookup c01b3595 t __lookup_tag c01b369d T radix_tree_gang_lookup_tag c01b36f0 T radix_tree_delete c01b3835 T radix_tree_tagged c01b3863 t radix_tree_node_ctor c01b3874 t __rb_rotate_left c01b38aa t __rb_rotate_right c01b38e0 T rb_insert_color c01b39a1 t __rb_erase_color c01b3b0c T rb_erase c01b3bcd T rb_first c01b3be5 T rb_last c01b3bfd T rb_next c01b3c26 T rb_prev c01b3c4f T rb_replace_node c01b3c94 T rwsem_wake c01b3d89 T rwsem_downgrade_wake c01b3e14 T strnicmp c01b3e75 T strcpy c01b3e89 T strncpy c01b3ea8 T strlcpy c01b3eeb T strcat c01b3f0a T strncat c01b3f35 T strlcat c01b3f97 T strcmp c01b3fae T strncmp c01b3fe0 T strchr c01b3ff0 T strrchr Cheers, Andrew Taylor Systems Engineer Array Systems Computing Inc. email: taylor@array.ca http: www.array.ca
