Author: n_hibma Date: Mon Jun 15 19:26:34 2009 New Revision: 194258 URL: http://svn.freebsd.org/changeset/base/194258 Log: Rearrange the init code in the stub driver, using a task to initialise the card. This allows better error handling and re-issuing of commands if one fails. Implement another initialisation sequence used buy the ZTE_STOR variants. Fix a bug where the driver would panic during initialisation reported by many (Mike Tancsa amongst others). Testing done and hardware supplied by belkin (a person, not the company).
