Since the Auto CMD23 feature is separate and none of my other patches depend on this, I would rather re-submit V3 patches except for the Auto CMD23 feature. Then once your patches have been accepted and tested, we can enable Auto CMD23 feature in the kernel. Let me know what you think. Sure, great! I've just mailed the v3 of my patch set, so I'm looking forward to any comments you have and any problems you uncover with Auto-CMD23. > >> Is there any kind of error injection mechanism you guys use to verify >> the error paths for Auto 12/23? > > None in particular. > I am starting to wish I had a "fake" MMC or SD card I could program to fail in various spectacular ways...
