???
The last MSG was just before the console gets started, so I don't think this is the cas unles there is something totally borked.
Another check:
# grep -i time /var/log/dmesg [17179569.184000] ACPI: PM-Timer IO Port: 0xee08 [17179569.184000] Using pmtmr for high-res timesource [17179570.672000] Calibrating delay using timer specific routine.. 1595.33 BogoMIPS (lpj=3190662) [17179570.772000] PCI: Setting latency timer of device 0000:00:01.0 to 64 [17179570.776000] Machine check exception polling timer started.

This is something new, I think:
[17179569.184000] ACPI: PM-Timer IO Port: 0xee08
or at least I don't remember seeing it before.
What is "time system" and how to check if it is up or not?
