Hello, I have an AMD K7 machine with an 8way RADI5 array on a Marvell based controller (sata_mv). When data is coming in over the Gigabit nic and is written to disk, messages like the one below intermittently shows up on the console. Eventually the machine freezes solid (hardware reset required). Kernel is 2.6.18 from kernel.org. Any idea what is going on? Regards, Fredrik Lindgren kernel: md0_raid5: page allocation failure. order:0, mode:0x20 kernel: <c013e17f> __alloc_pages+0x21f/0x310 <c0154415> kmem_getpages+0x35/0xa0 kernel: <c0155112> cache_grow+0xa2/0x160 <c01552fe> cache_alloc_refill+0x12e/0x1c0 kernel: <c01556e9> __kmalloc+0x69/0x70 <c03067e5> __alloc_skb+0x55/0x110 kernel: <c02a805f> skge_poll+0x41f/0x4c0 <c030cb3a> net_rx_action+0x6a/0xe0 kernel: <c011bebd> __do_softirq+0x7d/0x90 <c011bef6> do_softirq+0x26/0x30 kernel: <c0104ebe> do_IRQ+0x1e/0x30 <c01031be> common_interrupt+0x1a/0x20 kernel: <c02e6266> handle_stripe+0x6d6/0x1650 <c036f890> schedule+0x310/0x5c0 kernel: <c02e82a6> raid5d+0x86/0xe0 <c02f254e> md_thread+0x5e/0x130 kernel: <c01297a0> autoremove_wake_function+0x0/0x60 <c01297a0> autoremove_wake_function+0x0/0x60 kernel: <c02f24f0> md_thread+0x0/0x130 <c01293b1> kthread+0xb1/0xc0 kernel: <c0129300> kthread+0x0/0xc0 <c010139d> kernel_thread_helper+0x5/0x18 kernel: Mem-info: kernel: DMA per-cpu: kernel: cpu 0 hot: high 0, batch 1 used:0 kernel: cpu 0 cold: high 0, batch 1 used:0 kernel: DMA32 per-cpu: empty kernel: Normal per-cpu: kernel: cpu 0 hot: high 186, batch 31 used:30 kernel: cpu 0 cold: high 62, batch 15 used:55 kernel: HighMem per-cpu: empty kernel: Free pages: 4240kB (0kB HighMem) kernel: Active:38133 inactive:139270 dirty:19647 writeback:10 unstable:0 free:1060 slab:12120 mapped:6183 pagetables:236 kernel: DMA free:3032kB min:72kB low:88kB high:108kB active:36kB inactive:8624kB present:16384kB pages_scanned:0 all_unreclaimable?
