(Replies CC to list and direct to me please) Summary: -------- dmesg spammed with alloc_contig_range: [XX, YY) PFNs busy
Description: ------------ I recently upgrading 4.9-rc5, (previous kernel 4.5.0-rc6-00141-g6794402), and since then my dmesg has been absolutely flooded with 'PFNs busy' (>3GiB/day). My config did not change (all new options =n). It's not consistent addresses, so the squelch of identical printk lines hasn't helped. Eg output: [187487.621916] alloc_contig_range: [83f0a9, 83f0aa) PFNs busy [187487.621924] alloc_contig_range: [83f0ce, 83f0cf) PFNs busy [187487.621976] alloc_contig_range: [83f125, 83f126) PFNs busy [187487.622013] alloc_contig_range: [83f127, 83f128) PFNs busy Keywords: --------- mm, alloc_contig_range, CMA Most recent kernel version which did not have the bug: ------------------------------------------------------ Known 4.5.0-rc6-00141-g6794402 ver_linux: ---------- Linux bohr-int 4.9.0-rc5-00177-g81bcfe5 #12 SMP Wed Nov 16 13:16:32 PST 2016 x86_64 Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz GenuineIntel GNU/Linux GNU C 5.3.0 GNU Make 4.2.1 Binutils 2.25.1 Util-linux 2.29 Mount 2.29 Quota-tools 4.03 Linux C Library 2.23 Dynamic linker (ldd) 2.23 readlink: missing operand Try 'readlink --help' for more information.
