Do it in single user mode with udev helpers *killed*, but just release
the lever, _don't_ pull the drive off the bay, unless you do verify that
the bay LED went off.

***NEVER*** remove an Ultrabay device with the Ultrabay LED still lit,
especially if it is a PATA device.

If the bug cannot be reproduced in that condition, it is happening
because userspace is trapping the lever release event (as it should),
and doing something the kernel doesn't like with it (which is a bug
in the kernel in any case). That might help you track down a better
way to reproduce the issue.
