5.2.1 freezes on a nforce2 mainboard with apci, I have a nforce2 (same
abit board) based machine here running freebsd, never got the
5.2.1-release to work with acpi.
It was fixed a little while after the release, 5-current has been
running on the nforce2 for a while.
If you can wait untill the 5.3-release,which should be in about 2~3
weeks, (and run 5.2.1 without acpi for that time) I would do that, 5.3
no longer has the lock-up issue.
