So it seems it gets all the way to executing the initrd image,
which then fails to mount the root fs.

Earlier in the log:

ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata1.00: ATA-8: Hitachi HDT721025SLA380, STBOA3AA, max UDMA/133

so /dev/sda was detected. Is your root lvm volume on /dev/sda ?
Is /dev/VolGroup01/LogVol01 really your root fs?
