We have a dual-core AMD64 with the new kernel 2.6.14 and the timer goes backward... CONFIGURATION: Kernel: 2.6.14 Distribution: Gentoo Linux 2005.0 Processor: Athlon 64 x2 4200+ (dual core) Motherboard: Abit KN8 Memory: 1GB PC3200 PROBLEM: gettimeofday goes backward and returns values that are not monotonic, giving values that are smaller than values returned before. The system has been tested with timer as PIT, PIT/TSC and PM and the problem occurs with all the configurations. Here is the config file that we used for the PM configuration. Any suggestion ?Booting w/ idle=poll tends to work around this issue. You might check with your motherboard vendor for an updated BIOS that supports HPET or the ACPI PM timer.We already updated the BIOS with the latest version. Also the booting command idle=poll doesn't work.Hmm. Not sure then. Is this a new regression on the same hardware?Yes, we tried with idle=poll and the problem occurred again.
Very strange, idle=poll fixed it for us just fine. Configuration we use is as follows: Athlon 64 X2 3800+ Debian 32-bit Tyan K8E 4G PC3200 Vladimir
