page_alloc bug in 2.4.17-pre8

[Mike Black]

This machine had been up for 2-1/2 days and had run this backup (afio) twice successfully.

Here's line 108 of page_alloc.c:
        if (PageLRU(page))
                BUG();

Hopefully this doesn't indicate a CPU problem?  The power supply on this thing blew Saturday but has run OK until now.
