Author: mav Date: Thu Jun 18 07:50:27 2015 New Revision: 284540 URL: https://svnweb.freebsd.org/changeset/base/284540 Log: In case of target mode disable at least ISP2532 return invalid zero ct_rxid value on CTIO completion. Try to workaround that using tag_id from the CCB, pointed by still valid ct_syshandle. I don't know whether this is valid fix or dirty hack, but considering that alternative is indefinitely stuck command -- it worth trying.
