Hello Kefeng,

A change in remote port removal introduced a spurious put which

virtio_scsi tries to do exception handling after the default

control the timeout, otherwise with a heavy I/O load it is
likely that an abort will also timeout. This leads to fatal
errors like filesystems going offline.
