I am running 4.4-RELEASE with a custom kernel. While testing the box under heavy load it gives kernel panic and reboots. I have included the panic message and the nm output. I am not sure if its a bad memory problem, bad driver or bad gigabit card. I would really appreciate any suggestions or comments. Let me know if you need any other information. Thank you for your time and help. -Pranav ###### Panic Message #################### Fatal trap 12: page fault while in kernel mode fault virtual address = 0xd0004000 fault code = supervisor read, page not present instruction pointer = 0x8:0xc0326e90 stack pointer = 0x10:0xff3deb40 frame pointer = 0x10:0xff3deb4c code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 3 current process = 2956 (gzip) interrupt mask = net tty trap number = 12 panic: page fault ################################################ ####### Part of nm output close to the inst. pointer ############## c03260d8 t em_identify_hardware c0326214 t em_allocate_pci_resources c03262f8 t em_free_pci_resources c032635c t em_hardware_init c0326464 t em_read_mac_address c03264a8 t em_setup_interface c03265e4 t em_allocate_transmit_structures c0326650 t em_setup_transmit_structures c0326750 t em_initialize_transmit_unit c0326a08 t em_free_transmit_structures c0326a84 t em_transmit_checksum_setup c0326b8c t em_get_jumbo_buf c0326d54 t em_get_std_buf c0326fb0 t em_get_buf c0326fdc t em_allocate_receive_structures ################################################ ******************************************************************* Pranav A.
