data corruption using raid0+lvm2+jfs with 2.6.0-test3

[Tupshin Harper]

I have an LVM2 setup with four lvm groups. One of those groups sits on 
top of a two disk raid 0 array. When writing to JFS partitions on that 
lvm group, I get frequent, reproducible data corruption. This same setup 
works fine with 2.4.22-pre kernels. The JFS may or may not be relevant, 
since I haven't had a chance to use other filesystems as a control. 
There are a number of instances of the following message associated with 
the data corruption:

raid0_make_request bug: can't convert block across chunks or bigger than 
8k 12436792 8

The 12436792 varies widely, the rest is always the same. The error is 
coming from drivers/md/raid0.c.
