Hi All, I have kernel version 3.10.59. So during the allocation for skb i am getting call trace for __netdev_alloc_skb which follows till cache_alloc_refill and finally crashes. Please find snapshot below. addr2line -e vmlinux ffffffffc114109c shows linux/mm/slab.c:2700 has the problem. Is there any existing bug and any patch for this. Call Trace: [] *cache_alloc_refill*+0x1b4/0x848 [] __kmalloc_track_caller+0x124/0x1f0 [] __kmalloc_reserve.isra.17+0x40/0xa8 [] __alloc_skb+0x84/0x1a0 [] *__netdev_alloc_skb*+0xdc/0x148 [] xlpnae_irq+0x148/0x200 [] handle_irq_event_percpu+0x94/0x3f0 [] handle_irq_event+0x54/0x98 [] handle_level_irq+0xe4/0x170 [] generic_handle_irq+0x38/0x58 [] do_IRQ+0x18/0x28 [] plat_irq_dispatch+0x258/0x490 [] ret_from_irq+0x0/0x4 [] __r4k_wait+0x20/0x40 [] cpu_startup_entry+0xd4/0x2d8 [] prom_pre_boot_secondary_cpus+0x0/0x48 Thanks, Muazzam
