Tejun,
This Oops (2.6.23.13) looks very much like the same bug
you fixed recently for me in 2.6.24.
The bug was with sata_qstor and other drivers, in that
devres/libata were freeing the I/O resources before invoking
the LLD's host/port_stop routines .. which still need the I/O.
Did that patch get backported to 2.6.23 yet ?
No, it's not but yeah it probably should have. Tomasz, can you please
test whether the attached patch fixes the problem?
No oops anymore - I get those in the log instead (below).
START_STOP FAILED doesn't sound very good, but perhaps it's normal?
