Dear fglrx team, The newly submitted CAT 11.7 & sid's 11.8 have a glitch, "they loop madly on a sched_yield() call" (CKolivas - kscheduler). Both versions are usable desktopish but screw your system when utilizing GPUs for good (AMDstream, openCL). CPU usage 100%, System load ~7. Best regards Rüdiger Schiller
