I don't know an awful lot about oops messages, but since it mentions selinux_d_instantiate in there, I guess it has something to do with SELinux. I've printed the oops message below. Anyone have any idea what might be causing this? We're running reiserfs, so moving to the new SELinux would be problematic at this stage. Cheers, Paul ============================================================================== Unable to handle kernel NULL pointer dereference at virtual address 00000014 printing eip: c0199e04 *pde = 00000000 Oops: 0000 CPU: 0 EIP: 0010:[procfs_set_sid+236/260] Not tainted EFLAGS: 00010286 eax: 00000000 ebx: 00004567 ecx: dcc72000 edx: 00000001 esi: ee5e4c61 edi: d6e49a00 ebp: cecdffef esp: c8e59e40 ds: 0018 es: 0018 ss: 0018 Process ps (pid: 17768, stackpage=c8e59000) Stack: d6e49a00 00000000 c0255d92 c019a21a cde7aa80 ee5e4c00 ee5e4c30 cde7aa80 ee5e4c00 ee5e4c00 d6e49a24 ee5e4c00 cecdf000 c3c70d80 dcc72000 000000da c019e297 cde7aa80 ee5e4c00 c014b4ca ee5e4c00 cde7aa80 cde7aa80 dcc72000 Call Trace: [inode_doinit_with_dentry+1022/1084] [selinux_d_instantiate+19/24] [d_instantiate+42/96] [proc_pid_lookup+436/464] [proc_root_lookup+57/72] [real_lookup+122/268] [link_path_walk+748/2508] [path_walk+26/28] [path_lookup+27/36] [open_namei+137/1632] [filp_open+59/92] [sys_open+54/156] [system_call+51/56] Code: 8b 40 14 89 47 14 c6 47 38 01 89 c8 e8 17 6b f9 ff 5b 5e 5f ============================================================================== -- Paul Dwerryhouse | PGP Key ID: Amsterdam, The Netherlands (X) <-> Melbourne, Australia ( ) | 0x6B91B584 -- This message was distributed to subscribers of the selinux mailing list.
