17:42:42 Hi folks.  I believe that now you can detatch wdc/aic
pcmcia card on most  The restriction (I know or I can imagine)
is:  * the child device should be one of
atapibus/scsibus/sd/cd/wd.  if you   are using other devices,
for example if you have st or uk, you lose.  * if scsictl/atactl
is running, you may lose (as far as reading the   code.  I
should check this).  * of course if the deivce is opened with
read/write and the card is   removed without closing it, you may
lose.  * getdents(2) doesn't retun failiure while it should be
even if under   lying deivce is revoked.  some block device I/O
doesn't return   failure or it hangs if I/O is active.  anyway,
if you are digital camera user and you have compact flash card
and so on, this might help you.
