Stepmania freezes when xosd functions are used, in this case via app-laptop/tpb. Suspect it's a problem with only stepmania, as the problem does not occur with other OpenGL apps. Upon attempting to change volume and xosd is activated, step mania blanks screen and X becomes unresponsive. Laptop still responds to ACPI events, and X returns to normal after going to hibernation then back, with the following error from stepmania: r200WaitIrq: drmRadeonIrqWait: -16 ptrace failed: Operation not permitted ptrace failed: Operation not permitted ptrace failed: Operation not permitted [ebuild UD] games-arcade/stepmania-3.9_rc3 [3.9] -debug +gtk +jpeg +mad +mpeg +vorbis 0 kB [ebuild R ] x11-libs/xosd-2.2.8-r1 -xinerama -xmms 0 kB [ebuild R ] x11-base/xorg-x11-6.8.2-r7 -3dfx -3dnow +bitmap-fonts +cjk -debug -dlloader -dmx -doc -font-server -insecure-drivers +ipv6 -minimal +mmx +nls -nocxx +opengl +pam -sdk +sse -static +truetype-fonts +type1-fonts (-uclibc) +xprint +xv 0 kB (Same occurs with stepmania-3.9_rc3) This is running with xorg-x11 OpenGL driver.

Possibly a radeon driver problem? Apparently related to https://bugs.freedesktop.org/show_bug.cgi?id=1280
I can no longer reproduce this on newer but similar-ish hardware, and has received no confirmation, so closing.
