Hi,

That's interesting.  Would you mind trying to bisect?  (Knowing whether
2.6.38 final does it, for example, would be very helpful.)

There aren't many -EOPNOTSUPP returns in the stack.  I see:

card/block.c: mmc_blk_issue_secdiscard_rq and mmc_blk_issue_discard_rq
card/core.c: mmc_erase
core/sd_ops.c: mmc_app_cmd

Mind doing some instrumentation to figure out which it is?

Thanks,

- Chris.
