[Bug 553948] Re: WARNING: at /build/buildd/linux-2.6.32/mm/page_alloc.c:1806 __alloc_pages_slowpath+0x433/0x4a0()

[Amit Walambe]

I can see the __alloc_pages_slowpath error on a Thinkpad R61e running kernel 2.6.32-24-generic #38-Ubuntu SMP.
I haven't tested any mainline build yet.

The stack trace is as below.

I have seen a different but probably related error on the previous
kernel (2.6.32-23-generic #37-Ubuntu) :
