Dear Experts,

I have installed Solaris Express Developer Edition 9/07 on my notebook:
Fujitsu/Siemens Lifebook E8010,
Intel 1.8GHz,
1 GB RAM,
I855GME Chipset,
ATI M11 Mobility Radeon 9700 64MB VRAM

And I have following problem with my X server.
Sometimes after login, X server is interrupted when I move a cursor on my 
display or when I type something to Xterm. This cause that moving/writing is 
not done fluently and the graphical display is less usable.

After restart of X server or whole Solaris the problem often disappears. 


I have tried to analyze the problem.
First, I used prstat to see whenever the machine is somehow overloaded, but 
there was nothing. The CPU load was under 6%.
Therefore I used Dtrace to check Xorg process calls.
I have started a script in attachment and I have moved the cursor to simulate 
the interruption.
Afterwards I have tried also the same scenario on restarted system where the 
problem disappeared.
Both Dtrace logs are attached.

When the problem occurs Dtrace shows often usage of ?do_interrupt?.
When the X server works fine ?do_interrupt? is not called so often.

Can you please help me with that problem?
Can you tell me what?s wrong?
Is this a bug?

Thanks,
David.
