dmesg output
Try using a different clock source. I get: $ ./gettimeofday02 gettimeofday02 0 INFO : checking if gettimeofday is monotonous, takes 30s gettimeofday02 1 PASS : gettimeofday monotonous in 30 seconds $ uname -rmp 2.6.20-1.2962.fc6 x86_64 x86_64 My dmesg: time.c: Using 14.318180 MHz WALL HPET GTOD HPET/TSC timer. Yours says: time.c: Using 3.579545 MHz WALL PM GTOD PIT/TSC timer. Yes, that helped... clocksource of acpi_pm worked for me. (This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora! F8 on a different blade, same type of hardware: Time: tsc clocksource has been installed. # uname -rmp 2.6.23.9-85.fc8 x86_64 x86_64 # ./gettimeofday02 gettimeofday02 0 INFO : checking if gettimeofday is monotonous, takes 30s gettimeofday02 1 PASS : gettimeofday monotonous in 30 seconds |
