I'm still getting the "Invalidating pack" error on my test system,
using a 4.3-RC snapshot built from last night's CVS repository.

One thing I've noticed, however, is that it only occurs when I'm using
soft updates AND I'm installing across both drives on my test system.
If I install to only one drive, or don't use soft updates, the problem
does not manifest itself.  I've tried this many times and that's about
as best as I can "narrow" it down.  The relevent dmesg bits from
the affected system are:

Sorry I misidentified these drives as Quantums in my first failure
report.  They're clearly IBM drives.
