... while in kernel mode I get this while doing a ``return(COMPLETE);'' from dpt_scsi_cmd(), in response to the loop triggered by scsi_attachdevs(). It never happened until this morning. Last night I replaced a bunch of queue macros with functions. Quite unrelated. The functions are static inline, but I switched the inline part off and still the same result. The code is very innocent and appears to checkout OK. Maybe unrelated, but we have a few instances where calls to a function return the value from the previous call, rather than the current call, as in: char *foo(int yes) { if ( yes ) return("Yes"); return("No"); } printf("%s\n", foo(1)); ... < Produces "Yes" on the screen > printf("%s\n", foo(0)); ... < produces "No" on the screen > BUT... printf("%s-%s\n", foo(1), foo(0)); produces "Yes-Yes" instead of "Yes-No"... The actual example is much more complex, of course... :-( Any suggestions (the second case is much less important, but maybe it relates. The panic is a complete showstopper! Thanx! Simon BTW, whoever unsubscribed me from ALL FreeBSD lists - Please don't...
