--- Comment #6 from DaNiMoTh kronat@tiscali.it 2010-09-18 03:59:13 PDT --- Created an attachment (id=38780) --> (https://bugs.freedesktop.org/attachment.cgi?id=38780) error with agpmode=1

When system load radeon modules with agpmode=1, I had this error (fortunately I found it in /var/log/messages.log at next boot).

The lock happens more frequently, and give a black screen with no possibilities to switch to another console. There isn't operations which cause this lock more frequently than another: last time (this error) happens when I was scrolling an Opera window.
