I see. Thanks.



I'm not sure, but this problem might exist in all kernels since 2.6.18 , for
I can find clocksource= parameter in Documentation/kernel-parameters.txt .

I didn't experience this problem in earlier kernels (e.g. 2.6.20)
since I was running only 1 VMware guest at a time.
Today I ran 2 VMware guests simultaneously (one with kernel 2.6.22 and
the other with kernel 2.6.18, both are assigned 2 virtual CPUs) and I encountered
may-be-hanged-up with the 2.6.18 one.
The Ctrl-C didn't work, the Alt-F? didn't work, the Ctrl-Alt-Del didn't work.
I had no time to reproduce it, so I'm not sure it has actually hanged up.

Regards.
