I had to remove PG_swapbacked and PG_private2 as 2.6.26/2.6.27 didn't have those bits. After that, a comparison shows that this row is in 2.6.27, but not 2.6.26: 0x00020 20576 80 _____l____________ lru Unfortunately there are about 170 MB of missing memory, not 80. So we probably need to dig deeper. But does the above say anything to you? Rgds --=20 -- Pierre Ossman WARNING: This correspondence is being monitored by the Swedish government.
