Bug#533180: linux-image-amd64: page allocation failure within kernel swapper
I have the exact same problem as the original reporter with Debian lenny
and kernel 2.6.32-bpo.3-amd64 using a Core 2 Duo machine with 2GB of
RAM. I tested the RAM using memtest86 and did not find problems.
The failure seems to occur whenever heavy load is present, e.g.,
transferring big amounts of data between harddrives or the final linking
of a libwebkit build. Please find enclosed the relevant part of dmesg.
I'll be happy to provide additional information, please let me know
what could be helpful.
