LVM seems to be causing SCSI errors.

IIRC you said, that your test LVs spanned physical drives. Another known problem is flaky SCSI subsystem behaviour when LVM causes more load in configurations like this.

Can you trigger the problem, if you've got just one LV being allocated on one PV?

The problem is still there when the LVM is only on a single SCSI volume. In fact, changing the volume from one drive to the other shows SCSI errors on the new drive and the old drive used on a non LVM file system stops having errors.

What did the file system consistency check I mentioned in my other mail say?

When I ran an fsck on the file system with the errors (I did not re-do this experiment recently) it found bad blocks on the files system, but no inconsistencies on the file system itself.

Strange, running out of ideas here.
We don't have similar reports, do we?
