Problem Installing FC 6 Final on LVs over software raid

[Clyde E. Kunkel]

I have a test system comprised of an ASUS P4C800-Deluxe mobo with P4 
3.0GHz, two 120GB SATA drives on Promise SATA configured as IDE, two 
250GB SATA drives on Intel SATA configured as IDE and one 100GB drive on 
IDE used as a boot drive.

The system is used to test many different distributions including FC 5 
and Rawhide.  The boot drive has multiple partitions to keep the 
different distros separate and the SATA drives are completely 
partitioned as software raid autodetect and formed into software raid 5 
sets.  I then use LVs as the / partition for each distro.

I cannot get FC6 (or FC6T4, or Rawhide) to recognize one of the software 
raid partitions as a PV for the LVs.  It is listed as foreign in the 
anaconda partitioner.  HOWEVER, if the system was booted with FC5 or any 
other non-Fedora/Redhat distro before the attempted install, then the 
software raid 5 set is properly seen as a PV.  If the system was booted 
with a rawhide distro (originally installed during FC5 test days, and 
kept up-to-date) or a FC6T3 install, then that is when the raid set is 
seen as foreign.

I have tried every combination, including combinations from cold iron, 
and the same conditions prevail.  I can install FC6 final, just not on 
the VG that is on the foreign raid set or boot FC5 first.  I have run 
memtestx86 for hours without any failures.  I have tried with the DVD 
and with network install.

BZ http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=208947 was 
entered when the problem first occurred and it was a blocker to FC6 
release except the problem could not be reproduced by the developers.

I am hoping that one of the gurus who read this list can offer some help 
or an explanation.  I think there may be a clue in the last two 
attachments of the bz:  syslog of FC6 install attempt after booting FC5 
and syslog of FC6 install attempt after booting Rawhide.

Sending to test list per suggestion of Rahul.

TIA
