Hi all, Booting linux-next for 20140926 with CONFIG_PM_RUNTIME=N on a AM335X Beaglebone, I'm getting these sort of warnings for several devices (timer, uart, gpmc). config: http://sprunge.us/WGLM dmesg, CONFIG_PM_RUNTIME=y: http://sprunge.us/REhi dmesg, CONFIG_PM_RUNTIME=N: http://sprunge.us/YHFZ Any ideas? Here's an example of the warning: [ 0.217795] WARNING: CPU: 0 PID: 1 at /home/zeta/fast/linux/next/arch/arm/mach-omap2/omap_hwmod.c:2166 _enable+0x270/0x2ac() [ 0.217805] omap_hwmod: mpu: enabled state can only be entered from initialized, idle, or disabled state [ 0.217821] CPU: 0 PID: 1 Comm: swapper Tainted: G W 3.17.0-rc6-next-20140926-00001-g41b7528 #512 [ 0.217831] Backtrace: [ 0.217862] [<c0011b58>] (dump_backtrace) from [<c0011dc0>] (show_stack+0x18/0x1c) [ 0.217871] r6:c0024e64 r5:00000009 r4:df03fbf0 r3:00000000 [ 0.217898] [<c0011da8>] (show_stack) from [<c03ce568>] (dump_stack+0x20/0x28) [ 0.217917] [<c03ce548>] (dump_stack) from [<c00340cc>] (warn_slowpath_common+0x6c/0x8c) [ 0.217930] [<c0034060>] (warn_slowpath_common) from [<c0034158>] (warn_slowpath_fmt+0x38/0x40) [ 0.217937] r8:dfbd69d4 r7:00000001 r6:a0000113 r5:00000001 r4:c04fea44 [ 0.217965] [<c0034124>] (warn_slowpath_fmt) from [<c0024e64>] (_enable+0x270/0x2ac) [ 0.217972] r3:c047833c r2:c0478ecc [ 0.217990] [<c0024bf4>] (_enable) from [<c00256e8>] (omap_hwmod_enable+0x2c/0x4c) [ 0.217997] r7:00000001 r6:a0000113 r5:c04feaa4 r4:c04fea44 [ 0.218023] [<c00256bc>] (omap_hwmod_enable) from [<c0026a38>] (omap_device_enable+0x40/0x80) [ 0.218030] r6:df0ae780 r5:df0ae740 r4:00000000 r3:df0ae700 [ 0.218053] [<c00269f8>] (omap_device_enable) from [<c0026c5c>] (_omap_device_notifier_call+0x1e4/0x200) [ 0.218060] r5:df0b4c10 r4:df0ae740 [ 0.218088] [<c0026a78>] (_omap_device_notifier_call) from [<c004cc34>] (notifier_call_chain+0x4c/0x8c) [ 0.218095] r10:00000000 r9:00000000 r8:00000001 r7:df0b4c10 r6:00000000 r5:00000000 [ 0.218118] r4:ffffffff [ 0.218133] [<c004cbe8>] (notifier_call_chain) from [<c004d098>] (__blocking_notifier_call_chain+0x50/0x68) [ 0.218140] r8:00000000 r7:00000001 r6:df0b4c10 r5:ffffffff r4:df003908 r3:ffffffff [ 0.218168] [<c004d048>] (__blocking_notifier_call_chain) from [<c004d0d0>] (blocking_notifier_call_chain+0x20/0x28) [ 0.218175] r7:df0b4e10 r6:00000000 r5:df0b4c10 r4:df0b4c18 [ 0.218204] [<c004d0b0>] (blocking_notifier_call_chain) from [<c023eb04>] (device_add+0x3fc/0x50c) [ 0.218224] [<c023e708>] (device_add) from [<c0297f10>] (of_device_add+0x38/0x40) [ 0.218231] r9:dfbd69d4 r8:df0b4c00 r7:00000001 r6:c04e709c r5:00000000 r4:df0b4e10 [ 0.218259] [<c0297ed8>] (of_device_add) from [<c0298748>] (of_platform_device_create_pdata+0xe0/0x124) [ 0.218273] [<c0298668>] (of_platform_device_create_pdata) from [<c0298874>] (of_platform_bus_create+0xe8/0x194) [ 0.218280] r10:00000000 r9:df0b4e10 r8:c04eb0e4 r7:00000001 r6:c04e709c r5:dfbd69d4 [ 0.218303] r4:00000000 [ 0.218317] [<c029878c>] (of_platform_bus_create) from [<c02988d0>] (of_platform_bus_create+0x144/0x194) [ 0.218324] r10:00000000 r9:df0b4e10 r8:c04eb0e4 r7:00000001 r6:c04e709c r5:dfbd68f0 [ 0.218347] r4:dfbd69d4 [ 0.218361] [<c029878c>] (of_platform_bus_create) from [<c0298a74>] (of_platform_populate+0x64/0xa8) [ 0.218369] r10:c0520bc0 r9:00000001 r8:00000000 r7:c04e709c r6:c04eb0e4 r5:dfbd5ae0 [ 0.218391] r4:dfbd68f0 [ 0.218409] [<c0298a10>] (of_platform_populate) from [<c04caee8>] (pdata_quirks_init+0x3c/0x4c) [ 0.218416] r9:00000000 r8:c04c1aac r7:c04bf5e8 r6:df0aeb80 r5:c04eb0e4 r4:c04e7094 [ 0.218444] [<c04caeac>] (pdata_quirks_init) from [<c04cae90>] (omap_generic_init+0x18/0x24) [ 0.218451] r5:c04e59ec r4:c04e59ec [ 0.218472] [<c04cae78>] (omap_generic_init) from [<c04c1ad0>] (customize_machine+0x24/0x48) [ 0.218487] [<c04c1aac>] (customize_machine) from [<c04bfde4>] (do_one_initcall+0x108/0x1d0) [ 0.218500] [<c04bfcdc>] (do_one_initcall) from [<c04bffa8>] (kernel_init_freeable+0xfc/0x1c0) [ 0.218508] r10:c0520bc0 r9:c04e6220 r8:00000066 r7:c04bf5e8 r6:c0520bc0 r5:c04e6208 [ 0.218530] r4:00000003 [ 0.218553] [<c04bfeac>] (kernel_init_freeable) from [<c03caa64>] (kernel_init+0x10/0xf4) [ 0.218561] r10:00000000 r9:00000000 r8:00000000 r7:00000000 r6:00000000 r5:c03caa54 [ 0.218583] r4:00000000 [ 0.218598] [<c03caa54>] (kernel_init) from [<c000e668>] (ret_from_fork+0x14/0x2c) [ 0.218605] r4:00000000 r3:00000000 [ 0.218618] ---[ end trace cb88537fdc8fa202 ]--- -- Ezequiel Garcia, VanguardiaSur www.vanguardiasur.com.ar
