On one of my machines (Virtual machine running Debian on VMWare ESX OS), I unexpectedly got: "Clocksource tsc unstable (detlta = 4689558902 ns)" on my console.
I was able to get a login prompt with SSH, but after entering the username, the system freezes.
Resetting the VM in the VMWare console restored the VM to normal behaviour, but i would like to a) understand the error message and b) prevent it from happening again.
Can anybody shed some light on this for me? Using kernel 2.6.22-2-686 from the SID distribution, its a high volume production mail server. Some updates have been performed today but nothing really comes to mind that could be the culprit. Could it be a change on the VM host?
