Did your system fragmented in same way as to this (see DMA32, 10052 of order-0 pages) in older kernel ? I think you can check fragmentation status via /proc/buddyinfo. = kernel: Node 0 DMA: 3*4kB 3*8kB 5*16kB 2*32kB 4*64kB 1*128kB 2*256kB 0*512kB 1*1024kB 0*2048kB 0*4096kB = 2100kB kernel: Node 0 DMA32: 10062*4kB 1*8kB 1*16kB 0*32kB 1*64kB 1*128kB 0*256kB 1*512kB 0*1024kB 0*2048kB 0*4096kB = 40976kB == Thanks, -Kame -- To unsubscribe from this list: send the line "unsubscribe kernel-testers" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
