Is 2G RAM OK (by manually changing __PAGE_OFFSET ?)
Is this directly related to reiserfs (i.e. will it go away if I go back to using ext2 or switch to xfs?)
How serious is the problem? Can I get away with using it as is (with highmem) on a production server or will that cause serious repercussions?
Thanks,
Corin
