One possibility:

When we first tested 2.4.0-test8 on NetFinity 7000s we had random crashes,
typically within an hour of booting. The problem was identified as a Wiseman
Systems Management adapter generated hardware interrupt that 2.4 doesn't handle
(this was not a problem with 2.2.x).

If you have these adapters installed, remove them.
