    Thanks.

    After applying context_struct_to_string-not-leak.patch and reverting
    alloc_skb-false-positive.patch I haven't noticed that soft lockup.

    Here is something new
    orphan pointer 0xf40d61ac (size 1536):
    c017392a: <__kmalloc_track_caller>
    c01631b1: <__kzalloc>
    f98869cd: <skge_ring_alloc>
    f9888a1d: <skge_up>
    c02b17b6: <dev_open>
    c02b2e94: <dev_change_flags>
    c02e6e17: <devinet_ioctl>
    c02e8a02: <inet_ioctl>
