We have to fix this bug because local cache is always used for userland applications, e.g., iasl. BTW, I tried something like that long ago. In fact, the first attempt goes all the way back to this patch (warning: it's naive, broken, and overly complicated): http://people.freebsd.org/~jkim/acpica/OsdCache.diff I have more up-to-date and correct patch to use UMA but I'm still not 100% convinced whether we want to do it or not. When utcache.c works, it works fairly well, actually. :-) Jung-uk Kim -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iQEcBAEBAgAGBQJRAX15AAoJECXpabHZMqHOyoAH/i1eccONiETE+LiHlApmL+zy Y1h1D+R/S8hJ55fQ7i/2CkqAhNdHFI+TCrt2YIPNXS79VP9xyNRa+gPGHNqYUTF4 nv34ZpSi5MMERg7r+mOitNjPZfy+aiyDHI/PQFZ4lQR+by3c1HogKAwNPhLn0rxF NiA+X11lkcbBCxb4HzH8kSI5wFW/e5tEAHgGTrxJLzS1IGTbRBYLV6lA+ITBR0wu EzGw3FEU2pO2jDL3WxsM0vg/4VMCZvsnezxvRQ1XPbdJe4UU0ri3VgqzFX6N5ThI AeDuehji9lZiZc6Hjn35jSxq5KpzMiOj6bjLTEeO5zIdjmeGUWiMex+aoRrFOGU= =/bG6 -----END PGP SIGNATURE-----
