I'm experiencing a similar problem with a debian/etch xen host. Kernelis 2.6.18-6-xen-amd64 with the Steve Kemp's xen-utils-3.1.3-1 backport.
Devices are LVMs partitions from a SAN FC storage.
I've try with various device names, like xvd* but this didn't help.Part of my domU config file is:
root        = '/dev/xvda2 ro'
disk        = [
                  'phy:/dev/vg_domUs/nunki-swap,xvda1,w',
                  'phy:/dev/vg_domUs/nunki-root,xvda2,w',
                  'phy:/dev/vg_domUs/nunki-var,xvda3,w',
                  'phy:/dev/vg_domUs/nunki-usr,xvda4,w',
                  'phy:/dev/vg_domUs/nunki-tmp,xvda5,w',
                  'phy:/dev/vg_domUs/nunki-home,xvda6,w',
                  'phy:/dev/vg_domUs/nunki-var-log,xvda7,w',
                  'phy:/dev/vg_wdatas/www,xvdb1,w!'
              ]

(xvdb1 is an OCFS2 clustered partition which explains the w!)

Any idea will be greatly appreciated!

Besides upgrading to RHEL 5, as fast as you can? Or to CentOS 5?
