I was compiling glibc like I have done several times before, but the
last 3 times with the 2.6.20.x series of kernel when the testsuite runs
I get the following error. I've seen this issue reported on LKML but no
fixes. I'm compiling on a Netra T1.
Eeek! page_mapcount(page) went negative! (-1)
page pfn = 0
page->flags = 400
page->count = 1
page->mapping = 0000000000000000
vma->vm_ops = 0x8
