One issue (tested the -rc4 Version on -mm): - on interrupt flood (ping -f) HZ goes down to 0-4 HZ. This matches "ticks to skip" below. Coincidence?
- ping -f complains: .Warning: time of day goes back (-304us), taking countermeasures. ... .Warning: time of day goes back (-33us), taking countermeasures.
Yet, system time _seems_ to be kept correctly.
CPU is Pentium M.
dmesg: Using pmtmr for high-res timesource dyn-tick: Found suitable timer: pmtmr
dyn-tick: Maximum ticks to skip limited to 54 dyn-tick: Timer not enabled during boot
sysfs: suitable: 1 enabled: 1 using APIC: 0
