My bisect script pointed to the following kernel commit,

    SUNRPC: avoid race between mod_timer() and del_timer_sync()

    commit 3848e96edf4788f772d83990022fa7023a233d83 upstream.

    xprt_destory() claims XPRT_LOCKED and then calls del_timer_sync().
    Both xprt_unlock_connect() and xprt_release() call
     ->release_xprt()
    which drops XPRT_LOCKED and *then* xprt_schedule_autodisconnect()
    which calls mod_timer().

    This may result in mod_timer() being called *after* del_timer_sync().
    When this happens, the timer may fire long after the xprt has been freed,
    and run_timer_softirq() will probably crash.

    The pairing of ->release_xprt() and xprt_schedule_autodisconnect() is
    always called under ->transport_lock.  So if we take ->transport_lock to
    call del_timer_sync(), we can be sure that mod_timer() will run first
    (if it runs at all).

Prior to Linux 5.3, ->transport_lock needs spin_lock_bh() and 
spin_unlock_bh().

We get the same deadlock or similar one and we think that
can be connected to this thread on 4.19.243. For us is a bit
difficult to hit but we are going to apply this change

net: sunrpc: Fix deadlock in xprt_destroy

Prior to Linux 5.3, ->transport_lock needs spin_lock_bh() and
spin_unlock_bh().
