Public bug reported:
Binary package hint: linux-image-2.6.15-25-server
Here is the description of the bug, in the kernel's own words. I can't
try with version -27 of the kernel package now, since it won't boot
because of an initrd image problem. But I assume that unless this bug
was already reported to you and fixed by a patch you applied to your
latest kernel, it should still be present in -27...
