I have an oneiric domu install on a Debian 6 dom0.  My domu has a single / mount-point using ext4. 
The dom0 uses an lvm2 block device to present this disk to the domu.

Currently if I use pygrub and boot the oneiric 3.0.0-5 kernel my root filesystem gets remounted 

[    9.077887] end_request: I/O error, dev xvda2, sector 8651288
[    9.078258] end_request: I/O error, dev xvda2, sector 8651288
[    9.078642] Aborting journal on device xvda2-8.
[    9.101709] EXT4-fs error (device xvda2): ext4_journal_start_sb:296: Detected aborted journal
[    9.101730] EXT4-fs (xvda2): Remounting filesystem read-only

Currently I work-around this by booting the 2.6.32-5-xen Debian 6.0 kernel, but that means I end up 
running up against which is less 
than ideal.

I note there is mention in the server team minutes saying Xen has several issues, but I can't seem 
to find this particular issue within Launchpad?
