System: NetBSD bantha 7.0_BETA NetBSD 7.0_BETA (BANTHA) #4: Fri May 29 23:52:33 EDT 2015 root@bantha:/usr/src/sys/arch/i386/compile/BANTHA i386

>Description:
ktrace/kdump doesn't decode sysctls; it just prints the pointer
arguments of __sysctl(2).
3916 1 w CALL __sysctl(0xbfbfdd3c,2,0xbbbd54bc,0xbfbfdd38,0,0)
3916 1 w RET __sysctl 0
The average process issues a lot of sysctls and if one is trying to
debug something related to one, it's hard to be sure you've found the
one you're interested in.
Therefore, it would be nice if we could get at least the numeric mibs
and ideally the symbolic name. (This might require adding a new trace
record type.)
>How-To-Repeat:
ktrace w; kdump
>Fix:
to be argued over
