My entire system stops completely while unpacking large tar files, like when

This lasts about 0.5 seconds, then it starts working again, and then halts
again and so on, until the tarfile is completely uncompressed.
Is this expected behaviour? Is it a broken scheduler? Am I incuding something
in the kernel which I shouldn't have?
Sounds more like an interrupt issue.

Are you seeing interrupt storms?
What kind of controller are you using on that hard disk, and is
anything else sharing the same interrupt?

I've always had this problem (it sounds like the same thing at least)
with FreeBSD, on every system I have tried it on, be it 4.x or 5.x.
