Synopsis: panic: kernel page fault after calling cam_send_ccb State-Changed-From-To: open->analyzed State-Changed-By: gibbs State-Changed-When: Sun Aug 29 03:55:52 GMT 2004 State-Changed-Why: The constant '1' passed in ccb_flags tells CAM that the cdb data area contains a pointer to the CDB instead of the direct CDB bytes. This feature of the ANSI CAM spec is not universally supported by all CAM SIMs and most likely is not supported well by the XPT. We need to discuss whether this feature is worth preserving in CAM and how best to implement it to reduce the burden on SIM drivers. http://www.freebsd.org/cgi/query-pr.cgi?pr=61165
