Heyho! See stack trace at end. This seems to be the same issue; I also see a lot of these and the system is fine (including Internet connection over pppoe.) This is on a QNAP 419, running 2.6.32-2 plus a patch (I got this kernel from Martin Michlmayr because the QNAP 419 was not supported by Debian's kernel yet. I'll have to test one of these days if the patch has found its way in the -5 kernel package.) (QNAP means armel, btw. The machine has 512M RAM and runs a btrfs as raid over 4 disks -- I *think* btrfs might be quite memory hungry.) ===== [2110375.654112] pppoe: page allocation failure. order:1, mode:0x4020 [2110375.654176] [<c002d0b8>] (unwind_backtrace+0x0/0xdc) from [<c00a3d64>] (__alloc_pages_nodemask+0x4d4/0x584) [2110375.654217] [<c00a3d64>] (__alloc_pages_nodemask+0x4d4/0x584) from [<c00c7a24>] (__slab_alloc+0x170/0x52c) [2110375.654254] [<c00c7a24>] (__slab_alloc+0x170/0x52c) from [<c00c8490>] (__kmalloc+0x10c/0x19c) [2110375.654290] [<c00c8490>] (__kmalloc+0x10c/0x19c) from [<c01cddfc>] (tty_buffer_request_room+0xbc/0x124) [2110375.654326] [<c01cddfc>] (tty_buffer_request_room+0xbc/0x124) from [<c01cdfbc>] (tty_insert_flip_string+0x24/0x84) [2110375.654364] [<c01cdfbc>] (tty_insert_flip_string+0x24/0x84) from [<c01cebd4>] (pty_write+0x30/0x50) [2110375.654397] [<c01cebd4>] (pty_write+0x30/0x50) from [<c01c9f18>] (n_tty_write+0x2b8/0x3a0) [2110375.654429] [<c01c9f18>] (n_tty_write+0x2b8/0x3a0) from [<c01c7818>] (tty_write+0x180/0x21c) [2110375.654463] [<c01c7818>] (tty_write+0x180/0x21c) from [<c00cc2dc>] (vfs_write+0xac/0x1a0) [2110375.654496] [<c00cc2dc>] (vfs_write+0xac/0x1a0) from [<c00cc488>] (sys_write+0x40/0x6c) [2110375.654528] [<c00cc488>] (sys_write+0x40/0x6c) from [<c0026ea0>] (ret_fast_syscall+0x0/0x28) [2110375.654553] Mem-info: [2110375.654564] Normal per-cpu: [2110375.654577] CPU 0: hi: 186, btch: 31 usd: 166 [2110375.654602] active_anon:14982 inactive_anon:15313 isolated_anon:0 [2110375.654608] active_file:22690 inactive_file:44337 isolated_file:0 [2110375.654614] unevictable:0 dirty:11464 writeback:0 unstable:0 [2110375.654619] free:23329 slab_reclaimable:4519 slab_unreclaimable:1526 [2110375.654625] mapped:549 shmem:0 pagetables:487 bounce:0 [2110375.654696] Normal free:93316kB min:2884kB low:3604kB high:4324kB active_anon:59928kB inactive_anon:61252kB active_file:90760kB inactive_file:177348kB unevictable:0kB isolated(anon):0kB isolated(file):0kB present:520192kB mlocked:0kB dirty:45856kB writeback:0kB mapped:2196kB shmem:0kB slab_reclaimable:18076kB slab_unreclaimable:6104kB kernel_stack:656kB pagetables:1948kB unstable:0kB bounce:0kB writeback_tmp:0kB pages_scanned:0 all_unreclaimable? no [2110375.654786] lowmem_reserve[]: 0 0 [2110375.654801] Normal: 23295*4kB 1*8kB 2*16kB 1*32kB 1*64kB 0*128kB 0*256kB 0*512kB 0*1024kB 0*2048kB 0*4096kB = 93316kB [2110375.654851] 74987 total pagecache pages [2110375.654864] 7964 pages in swap cache [2110375.654879] Swap cache stats: add 2573509, delete 2565545, find 502748/881838 [2110375.654900] Free swap = 1466720kB [2110375.654912] Total swap = 2008084kB [2110375.663084] 131072 pages of RAM [2110375.663105] 23663 free pages [2110375.663117] 2382 reserved pages [2110375.663129] 5328 slab pages [2110375.663140] 84010 pages shared [2110375.663152] 7964 pages swap cached [2110375.663167] SLUB: Unable to allocate memory on node -1 (gfp=0x20) [2110375.663189] cache: kmalloc-8192, object size: 8192, buffer size: 8192, default order: 3, min order: 1 [2110375.663216] node 0: slabs: 4, objs: 16, free: 0 [2261975.032056] udev: starting version 150 -- The ants in France, stay mainly on the plants.
