Hi Fabio,

Are you able to reproduce this freeze with current oneiric?

If so, please collect a mmiotrace on the bug.

 $ mount -t debugfs debugfs /sys/kernel/debug
 $ echo mmiotrace > /sys/kernel/debug/tracing/current_tracer
 $ cat /sys/kernel/debug/tracing/trace_pipe > mydump.txt &
 Start X or whatever.
 $ echo "X is up" > /sys/kernel/debug/tracing/trace_marker
 $ echo nop > /sys/kernel/debug/tracing/current_tracer
 Check for lost events.

For more help on using mmiotrace, see http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=Documentation/trace/mmiotrace.txt
