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?
