Sorry for the late followup.
The next release of Debian (6.0, code name Squeeze) will be based
on 2.6.32. Please test the current 2.6.32 from unstable/testing and tell
us whether the problem persists. If so, we should report it upstream
to the kernel.org developers.
The 2.6.32 kernel is available from packages.debian.org and can
be installed in both Debian stable, testing and unstable
