One observation is that dpll4_m5x2_ck and dpll4_m6x2_ck are never enabled. The tracebacks occur when something in the suspend path tries to disable those clocks. - Paul [ 0.135528] enabling clkdm dpll4_clkdm during enable of clk dpll4_ck [ 0.135559] clockdomain: dpll4_clkdm: enabled [ 0.135589] enabling clkdm dpll4_clkdm during enable of clk dpll4_m2x2_ck [ 0.135681] disabling clkdm dpll4_clkdm during disable of clk dpll4_m2x2_ck [ 0.135681] disabling clkdm dpll4_clkdm during disable of clk dpll4_ck [ 0.135711] clockdomain: dpll4_clkdm: disabled [ 0.135772] enabling clkdm dpll4_clkdm during enable of clk dpll4_ck [ 0.135803] clockdomain: dpll4_clkdm: enabled [ 0.135833] enabling clkdm dpll4_clkdm during enable of clk dpll4_m2x2_ck [ 0.135894] disabling clkdm dpll4_clkdm during disable of clk dpll4_m2x2_ck [ 0.135925] disabling clkdm dpll4_clkdm during disable of clk dpll4_ck [ 0.135955] clockdomain: dpll4_clkdm: disabled [ 0.135986] enabling clkdm dpll4_clkdm during enable of clk dpll4_ck [ 0.136016] clockdomain: dpll4_clkdm: enabled [ 0.136047] enabling clkdm dpll4_clkdm during enable of clk dpll4_m2x2_ck [ 0.136138] disabling clkdm dpll4_clkdm during disable of clk dpll4_m2x2_ck [ 0.136169] disabling clkdm dpll4_clkdm during disable of clk dpll4_ck [ 0.136169] clockdomain: dpll4_clkdm: disabled [ 0.136260] enabling clkdm dpll4_clkdm during enable of clk dpll4_ck [ 0.136291] clockdomain: dpll4_clkdm: enabled [ 0.136322] enabling clkdm dpll4_clkdm during enable of clk dpll4_m2x2_ck [ 0.140594] enabling clkdm dpll4_clkdm during enable of clk dpll4_m4x2_ck [ 0.140686] enabling clkdm dpll4_clkdm during enable of clk dpll4_m3x2_ck [ 0.140838] disabling clkdm dpll4_clkdm during disable of clk dpll4_m3x2_ck [ 0.140930] disabling clkdm dpll4_clkdm during disable of clk dpll4_m4x2_ck [ 0.141479] enabling clkdm dpll4_clkdm during enable of clk dpll4_m4x2_ck [ 0.141571] disabling clkdm dpll4_clkdm during disable of clk dpll4_m4x2_ck [ 0.141601] enabling clkdm dpll4_clkdm during enable of clk dpll4_m4x2_ck [ 0.141662] disabling clkdm dpll4_clkdm during disable of clk dpll4_m4x2_ck [ 0.141693] enabling clkdm dpll4_clkdm during enable of clk dpll4_m4x2_ck [ 0.141784] disabling clkdm dpll4_clkdm during disable of clk dpll4_m4x2_ck [ 0.141815] enabling clkdm dpll4_clkdm during enable of clk dpll4_m3x2_ck [ 0.141876] disabling clkdm dpll4_clkdm during disable of clk dpll4_m3x2_ck [ 3.399200] disabling clkdm dpll4_clkdm during disable of clk dpll4_m6x2_ck [ 3.417694] [<c001c1cc>] (unwind_backtrace+0x0/0xf0) from [<c0043680>] (warn_slowpath_common+0x4c/0x64) [ 3.445251] ---[ end trace 72e2d7bdcf98ea8b ]--- [ 3.450134] disabling clkdm dpll4_clkdm during disable of clk dpll4_m5x2_ck [ 3.453918] clockdomain: dpll4_clkdm: disabled [ 3.477569] [<c001c1cc>] (unwind_backtrace+0x0/0xf0) from [<c0043680>] (warn_slowpath_common+0x4c/0x64) [ 3.505096] ---[ end trace 72e2d7bdcf98ea8c ]--- [ 3.531280] [<c001c1cc>] (unwind_backtrace+0x0/0xf0) from [<c0043680>] (warn_slowpath_common+0x4c/0x64) [ 3.558807] ---[ end trace 72e2d7bdcf98ea8d ]--- [ 38.999145] disabling clkdm dpll4_clkdm during disable of clk dpll4_m2x2_ck [ 38.999267] [<c001c1cc>] (unwind_backtrace+0x0/0xf0) from [<c0043680>] (warn_slowpath_common+0x4c/0x64) [ 38.999816] ---[ end trace 72e2d7bdcf98ea8e ]--- [ 38.999816] disabling clkdm dpll4_clkdm during disable of clk dpll4_ck [ 38.999908] [<c001c1cc>] (unwind_backtrace+0x0/0xf0) from [<c0043680>] (warn_slowpath_common+0x4c/0x64) [ 39.000366] ---[ end trace 72e2d7bdcf98ea8f ]--- [ 42.169647] enabling clkdm dpll4_clkdm during enable of clk dpll4_ck [ 42.169647] clockdomain: dpll4_clkdm: enabled [ 42.169677] enabling clkdm dpll4_clkdm during enable of clk dpll4_m2x2_ck [ 45.730346] [<c001c1cc>] (unwind_backtrace+0x0/0xf0) from [<c0043680>] (warn_slowpath_common+0x4c/0x64) [ 45.795654] ---[ end trace 72e2d7bdcf98ea90 ]--- -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
