Subject: libata /dev/scd0 problem: mount after burn fails without eject

Tested on 2.6.20.6 and 2.6.21.1

I decided to swich from the old IDE drivers to libata and now there
seems to be a little but annoying problem: cannot mount an ISO image
after burning it.

May 1 14:32:55 kernel: attempt to access beyond end of device
May 1 14:32:55 kernel: sr0: rw=0, want=68, limit=4
May 1 14:32:55 kernel: isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16

an "eject" command seems to fix the state of the PATA DVD writer
or driver. The problem occurs for burning a CD and for DVD too with
identical error messages.

relevant kernel boot messages:

I'm not sure if that's "proper" or not, but such has always been the case
here. Even k3b has been ejecting and remounting the cd/dvd since forever
when it is asked to do a verify pass.
