I saw it on kernel 3.18 as well. As an aside I semi-bricked my router and I'm currently unable to flash new images - unfortunate, as I prepped an OpenWRT build with debug logging. I feel committed to seeing this through though so I have another device ordered but I will be unable to test new builds until it gets here in a week or so. -- David Gilman :DG< http://gilslotd.com --XF85m9dhOBO43t/C Content-Type: text/plain; charset=us-ascii Content-Disposition: attachment; filename=openwrt_old_syslog [ 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Linux version 4.4.7 (openwrt@0e997fc2ad25) (gcc version 5.3.0 (OpenWrt GCC 5.3.0 r49377) ) #1 Sun May 22 08:20:37 UTC 2016 [ 0.000000] CPU: Feroceon 88FR131 [56251311] revision 1 (ARMv5TE), cr=0005397f [ 0.000000] CPU: VIVT data cache, VIVT instruction cache [ 0.000000] Machine model: Linksys EA3500 [ 0.000000] Memory policy: Data cache writeback [ 0.000000] On node 0 totalpages: 16384 [ 0.000000] free_area_init_node: node 0, pgdat c057d838, node_mem_map c3f7a000 [ 0.000000] Normal zone: 128 pages used for memmap [ 0.000000] Normal zone: 0 pages reserved [ 0.000000] Normal zone: 16384 pages, LIFO batch:3 [ 0.000000] pcpu-alloc: s0 r0 d32768 u32768 alloc=1*32768 [ 0.000000] pcpu-alloc: [0] 0 [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on.
