I seem to have run into some sort of regression in the SG_IO interface

The 2.6.23.16 kernel works fine.
During reads I get these kernel messages. Writes and other functions
_seem_ OK. Actually basic
reads are working. Its with large BC reads using an io_vec list that
the problem shows up.
Are you doing SG_IO to the sg device (/dev/sg*) or to the block device
(/dev/sdX)?
If you are doing SG_IO to the sg device, then I know of one regression
(well not regression exactly, but I fixed a bug but the patch got
partially overwritten by another patch and that caused a new bug). Both
bugs are fixed in 2.6.25-rc2. Could you try that out if you are doing
SG_IO to the sg device.
