There appears to be a bug in umount on slow devices (and in principle on
faster ones). umount invalidates the entries in the buffer cache by setting
their b_dev field to -1. However, slow devices like RK05s and RX02s, when
they finally get around to looking at these entries some time later, find
that they point to non-existant devices (like minor device 7 in the case of
the RK05). Is there a standard fix for this problem?
