Does a 2.4.21-pre3 kernel work?

I've seen this as well when I attempted to upgrade a system with 2
raid0, and 1 raid1 devices. It was a Intel se7500wv, 4G memory, and two
3ware 7500-8. The system works just fine with old aa's, and redhat's
2.4.18-19 kernel. I didn't have much time to spend with it, and I was
waiting to test 2.4.21-pre3 before reporting the bug.

There is no such thing as obsolete hardware.
Merely hardware that other people don't want.
