Unfortunately, that appears to not be a universal fix. The current public KnoppMyth R5E50 already has the kernel configured for 1000, and yet the problem remains: --- [EMAIL PROTECTED]:/lib/modules/2.6.18-chw-13/build# grep HZ .config # CONFIG_HZ_100 is not set # CONFIG_HZ_250_NODEFAULT is not set CONFIG_HZ_1000=y CONFIG_HZ=1000 --- -brendan _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
