Did anyone find a solution to the "jerky mouse" -problem? It still exists in 7.0-RELEASE.
I have pretty much exact same symptoms as in this post:
http://lists.freebsd.org/pipermail/freebsd-stable/2008-January/039599.html
Part of the problem here is that these "symptoms" are far too generic for diagnosis and have a variety of known and unknown causes.
Some of the "known" causes include:
* Overloading the system transiently (e.g. if your KDE launches 30 processes at once, the system is going to be a bit sluggish for a few seconds)
* Running powerd, which has poor interaction with interrupt delivery on at least one user's system (might be an ACPI issue or hardware-specific).
* Performing lots of I/O to a non-mpsafe filesystem like msdosfs.
The other causes have so far resisted understanding.
