Hi all. I updated from a 3.14 kernel to 3.15-rc5 kernel and have from time to time some problems. With the 3.14 kernel kernel I have never seen this problem - I am using this device to do some vivante gpu driver development. debian@arm:~$ dmesg (I removed drm.debug messages) [ 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Initializing cgroup subsys cpuacct [ 0.000000] Linux version 3.15.0-rc5+ (debian@arm) (gcc version 4.6.3 (Debian 4.6.3-14) ) #6 SMP Thu May 15 20:05:36 UTC 2014 [ 0.000000] CPU: ARMv7 Processor [412fc09a] revision 10 (ARMv7), cr=10c5387d [ 0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache [ 0.000000] Machine model: Freescale i.MX6 Quad SABRE Lite Board [ 0.000000] cma: CMA: reserved 16 MiB at 3e800000 [ 0.000000] Memory policy: Data cache writealloc [ 0.000000] On node 0 totalpages: 262144 [ 0.000000] free_area_init_node: node 0, pgdat c0812d40, node_mem_map edff1000 [ 0.000000] Normal zone: 1520 pages used for memmap [ 0.000000] Normal zone: 0 pages reserved [ 0.000000] Normal zone: 194560 pages, LIFO batch:31 [ 0.000000] HighMem zone: 528 pages used for memmap [ 0.000000] HighMem zone: 67584 pages, LIFO batch:15 [ 0.000000] PERCPU: Embedded 9 pages/cpu @edfaf000 s13760 r8192 d14912 u36864 [ 0.000000] pcpu-alloc: s13760 r8192 d14912 u36864 alloc=9*4096 [ 0.000000] pcpu-alloc: [0] 0 [0] 1 [0] 2 [0] 3 [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on.
