Context: I've updated to ports r368074 which updated Xorg, the drivers, and even gcc (to 4.8.3). I used portmaster -t -D -a. This was on... FreeBSD FBSDG4S0 10.1-PRERELEASE FreeBSD 10.1-PRERELEASE #0 r271215: Sat Sep 6 23:56:15 PDT 2014 root@FBSDG4S0:/usr/obj/usr/src/sys/GENERIC powerpc After this during an example logout from xfce4 I've gotten an example of the EQ overflowing notices for: NVIDIA GeForce4 Ti 4600 when used at 1680x1050 on a PowerMac G4 Dual (1.4 GHz FW800) Generally these EQ overflow messages seem to be tied to logout or Option-Fn in basic use. (This is still an syscons context by default for powerpc. At least Xorg.0.log reports that syscons is what is in use.) So far I do not get these kinds of notices systematically for this context. Just infrequently. === Mark Millard markmi at dsl-only.net On Sep 12, 2014, at 9:58 PM, Mark Millard <markmi at dsl-only.net> wrote: Hi.
