Responsible-Changed-From-To: freebsd-bugs->harti Responsible-Changed-By: harti Responsible-Changed-When: Fri Aug 13 11:03:15 GMT 2004 Responsible-Changed-Why: I take this. The reason for the core is quite obvious from the backtrace: the interrupt handler CompatInterrupt call free() which it shouldn't do. In general interrupt handlers are allowed to call only a small number of functions. This will require some work, though. http://www.freebsd.org/cgi/query-pr.cgi?pr=29103
