Are you running on a 64-bit kernel, is your clocksource hpet and is vsyscall64 on? $ uname -m x86_64 $ cat /sys/devices/system/clocksource/clocksource0/current_clocksource hpet $ cat /proc/sys/kernel/vsyscall64 1 If so, try putting this into your /etc/sysctl.conf and rebooting: # vsyscall64 off kernel.vsyscall64 = 0 You could try echoing "1" into /proc/sys/kernel/vsyscall64, but with the keyboard doubling issue, it might be a problem :) Clark -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkejRsMACgkQHyuj/+TTEp14GgCg1PV1n23nDDJg8Bp6NTEXIUTQ iukAoK56x+wQcZ8Z+YNea8glzIe41EpA =ZKru -----END PGP SIGNATURE----- - To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
