atacontrol detach freezes -STABLE?

Hi,

For over a year now, I've been hot-swapping devices from the modular bay 
in my Omnibook by ensuring that any filesystem is umounted first (bad 
things happen if you forget this, duh!), doing an 'atacontrol detach 1', 
plugging in the new device and re-attaching the ATA channel.

It's been working flawlessly, (and a very useful facility it is too). 

I recently updated to -STABLE from Mar 12, and this no longer seems to 
work 100%. I sometimes get away with detaching the CD-ROM, but the whole 
system is very likely to lock hard (with or without the drive LED on 
solid) either immediately or within 5-10 seconds after popping the 
modular device out.

Detaching the secondary HDD is very much less likely to work, I think 
it's worked once or twice for about 15-20 failures.

I /think/ I can increase my chances of getting away with it by waiting 
for a couple of minutes before ejecting - but this never used to be an 
issue.

Has anything changed recently that might have an impact on this?

TIA,

AS
