I experience the same, running Ubuntu-10.4-alpha2 on my HD3850.
Logs look quite normal as far as I can tell.
I experience very low performance, and many visual artifacts even when
running without composition manager.

Should I open a bug-report about the corruptions and attache
log&screenshots or are those problems known and to be expected due to
the experimental nature of radeon-kms?
