... 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
