That commit causes several problems in Linux as described in the BZ.
In particular, after a while, other devices on the bus are no longer
usable even if those devices are not affected by the hotunplug.
This may be a problem in Linux, but we have not been able to identify
it so far. So better to revert this patch until we find a solution.

Also, Oracle, which initially proposed this patch for a problem with
Solaris, seems to have already reversed it downstream:
