I've got an old PIII 256M Ram PC that for years has served as an always on TV streamer/recorder and gateway/server box. It had 2 PCI dvb cards until now I have a PCTV 290e so replaced one card with a USB2 PCI card. At first the PCTV worked OK, but now I've been getting a page allocation failure. After this happens I can't use the PVTV until I re-plug it. It will then work, but the next day I am likely to get the same. Free/meminfo (to my untrained eye) seem to show available mem. mumudvb: page allocation failure: order:4, mode:0x80d0 Pid: 15776, comm: mumudvb Not tainted 3.3.0-rc1 #6 Call Trace: [] ? printk+0x1b/0x20 [] warn_alloc_failed+0xc3/0x130 [] __alloc_pages_nodemask+0x447/0x580 [] dma_generic_alloc_coherent+0x68/0xe0 [] hcd_buffer_alloc+0x101/0x110 [] ? dma_set_mask+0x50/0x50 [] usb_alloc_coherent+0x25/0x30 [] em28xx_init_isoc+0x10c/0x360 [em28xx] [] em28xx_start_feed+0xad/0xe0 [em28xx_dvb] [] ? em28xx_mt352_terratec_xs_init+0x120/0x120 [em28xx_dvb] [] dmx_ts_feed_start_filtering+0x4c/0xd0 [dvb_core] [] dvb_dmxdev_start_feed+0x9d/0xf0 [dvb_core] [] dvb_dmxdev_filter_start+0x269/0x380 [dvb_core] [] ? dvb_dmxdev_add_pid+0x51/0xa0 [dvb_core] [] dvb_demux_do_ioctl+0x164/0x550 [dvb_core] [] ? path_put+0x15/0x20 [] ? do_last+0x1e4/0x7d0 [] ? _copy_from_user+0x37/0x60 [] dvb_usercopy+0xef/0x1a0 [dvb_core] [] ? do_filp_open+0x30/0x80 [] ? dvb_dmxdev_start_feed+0xf0/0xf0 [dvb_core] [] dvb_demux_ioctl+0x12/0x20 [dvb_core] [] ? dvb_demux_release+0x160/0x160 [dvb_core] [] vfs_ioctl+0x31/0x50 [] do_vfs_ioctl+0xaa/0x500 [] ? getname_flags+0xc3/0x130 [] ? fd_install+0x48/0x60 [] ? do_sys_open+0x16b/0x1b0 [] ? handle_vm86_fault+0x160/0x910 [] sys_ioctl+0x39/0x70 [] sysenter_do_call+0x12/0x26 Mem-Info: DMA per-cpu: CPU 0: hi: 0, btch: 1 usd: 0 Normal per-cpu: CPU 0: hi: 90, btch: 15 usd: 0 active_anon:806 inactive_anon:10372 isolated_anon:0 active_file:21713 inactive_file:22283 isolated_file:0 unevictable:0 dirty:45 writeback:0 unstable:0 free:994 slab_reclaimable:2584 slab_unreclaimable:1960 mapped:1002 shmem:12 pagetables:409 bounce:0 DMA free:1100kB min:124kB low:152kB high:184kB active_anon:52kB inactive_anon:72kB active_file:6008kB inactive_file:8136kB unevictable:0kB isolated(anon):0kB isolated(file):0kB present:15808kB mlocked:0kB dirty:4kB writeback:0kB mapped:12kB shmem:0kB slab_reclaimable:436kB slab_unreclaimable:16kB kernel_stack:24kB pagetables:0kB unstable:0kB bounce:0kB writeback_tmp:0kB pages_scanned:0 all_unreclaimable? no lowmem_reserve[]: 0 237 237 Normal free:2756kB min:1904kB low:2380kB high:2856kB active_anon:3172kB inactive_anon:41416kB active_file:80844kB inactive_file:80996kB unevictable:0kB isolated(anon):0kB isolated(file):0kB present:242824kB mlocked:0kB dirty:176kB writeback:0kB mapped:3996kB shmem:48kB slab_reclaimable:9900kB slab_unreclaimable:7824kB kernel_stack:1904kB pagetables:1636kB unstable:0kB bounce:0kB writeback_tmp:0kB pages_scanned:0 all_unreclaimable? no lowmem_reserve[]: 0 0 0 DMA: 277*4kB 0*8kB 0*16kB 0*32kB 0*64kB 0*128kB 0*256kB 0*512kB 0*1024kB 0*2048kB 0*4096kB = 1108kB Normal: 233*4kB 202*8kB 5*16kB 0*32kB 2*64kB 0*128kB 0*256kB 0*512kB 0*1024kB 0*2048kB 0*4096kB = 2756kB 44485 total pagecache pages 476 pages in swap cache Swap cache stats: add 1563, delete 1087, find 1624/1719 Free swap = 485904kB Total swap = 488340kB 65264 pages RAM 1946 pages reserved 49870 pages shared 36872 pages non-shared unable to allocate 60160 bytes for transfer buffer 0
