Subject: Linux 2.6.25-rc2 regression: LVM cannot find volume group

2.6.25-rc2 fails to bring up my openSUSE 10.3 PC because LVM
cannot find the volume group containing the root file system.
2.6.25-rc1 has the same problem, 2.6.24 works fine.

Config attached. Architecture is x86 32bit. The two SATA disks are
hanging off an ICH6. More detail on request.

Anything obvious? Bisect?
