Extra battery causes hangs (T40p, FreeBSD 5.1/CURRENT)

Really? 4.x with APM handles swapping between a secondary HDD, CD-ROM, 
DVD & DVD/CD-RW in the secondary bay on my Omnibook just fine.

I never managed to obtain a secondary battery so haven't tried that - 
but I'd expect disabling/ejecting/inserting dissimilar mass storage 
devices to make the OS cranky if anything did.

I thought that was what atacontrol detach/attach were intended for... 
Does this not exist on 5.x?

Cheers,
