Hi all, it seems crash shows incorrect HighMem stats with recent kernels. E.g.: crash> kmem -i [...] TOTAL HIGH 1821682 6.9 GB 93% of TOTAL MEM FREE HIGH 0 0 0% of TOTAL HIGH TOTAL LOW 132983 519.5 MB 6% of TOTAL MEM FREE LOW 1333474 5.1 GB 1002% of TOTAL LOW BTW note that total low is smaller than free low, which is obviously incorrect. I believe that this is somehow related to the Movable zone, because the code that counts free low pages checks for pages which belong to ZONE_HIGHMEM, which is initialized as: vt->ZONE_HIGHMEM = vt->nr_zones - 1; My system has 4 zones: ZONE NAME SIZE MEM_MAP START_PADDR START_MAPNR 0 DMA 4080 f4a02200 10000 0 1 Normal 221694 f4a22000 1000000 4080 2 HighMem 790002 f50e5fc0 371fe000 225774 3 Movable 0 0 0 0 And indeed, "help -v" shows: [...] dump_free_pages: dump_free_pages_zones_v2() [...] ZONE_HIGHMEM: 3 I don't know yet how to fix this, but maybe somebody can push me in the right direction.
