Hi All, I am running a SUSE linux 3.0.13-0.27 and after printing an opps the system hangs (though it only happened once). In the opps there is only Code: information, no stack trace or processor registers. Analyzing the code most of the cores are in intel_idle function, but there is also appears native_read_tsc and delay_tsc.
Any help would be more than welcome. Attached the console output: [2718229.308036] Stack: [2718229.334021] Call Trace: [2718229.365203] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [2718229.592831] Stack: [2718229.618815] Call Trace: [2718229.619910] Leftover inexact backtrace: [2718229.619910] [2718229.619911] <IRQ> [2718229.619913] <EOI> [2718229.619914] Code: 98 45 89 ef 48 89 04 24 eb 16 66 0f 1f 44 00 00 f3 90 65 44 8b 34 25 70 c5 00 00 45 39 fe 75 2b 66 66 90 0f ae e8 e8 cd 9a db ff [2718229.620741] Stack: [2718229.620748] Call Trace: [2718229.620761] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [2718229.620825] Stack: [2718229.620833] Call Trace: [2718229.620842] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [2718229.621012] Stack: [2718229.621020] Call Trace: [2718229.621036] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [2718229.621115] Stack: [2718229.621122] Call Trace: [2718229.621132] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [2718229.621205] Stack: [2718229.621212] Call Trace: [2718229.621222] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [2718229.621422] Stack: [2718229.621429] Call Trace: [2718229.621446] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [2718229.621551] Stack: [2718229.621564] Call Trace: [2718229.621579] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [4194339.646298] Stack: [4194339.672279] Call Trace: [4194339.704539] Leftover inexact backtrace: [4194339.704539] [4194339.772037] <IRQ> [4194339.796922] <EOI> [4194339.826073] Code: 70 e4 71 c3 0f 1f 80 00 00 00 00 40 0f b6 c6 e6 70 40 0f b6 c7 e6 71 c3 0f 1f 00 0f 31 89 c1 48 89 d0 48 c1 e0 20 89 ca 48 09 d0 <c3> 66 66 66 66 66 66 2e 0f 1f 84 00 00 00 00 00 48 83 ec 18 48 [4194340.054808] Stack: [4194340.080786] Call Trace: [4194340.111957] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [4194340.339554] Stack: [4194340.365534] Call Trace: [4194340.396700] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [4194340.624288] Stack: [4194340.650267] Call Trace: [4194340.681435] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [4194340.909073] Stack: [4194340.935054] Call Trace: [4194340.966222] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [4194341.193816] Stack: [4194341.219796] Call Trace: [4194341.250969] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [4194341.478549] Stack: [4194341.504530] Call Trace: [4194341.535696] Code: 01 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 00 48 8d 74 24 2c bf [4194341.763335] Stack: BIOS Date: 12/27/10 16:47 e8 5d 41 5c c3 0f 1f 40 00 31 c9 48 89 f0 48 89 ca 0f 01 c8 0f ae f0 48 8b 87 38 e0 ff ff a8 08 75 88 b1 01 48 89 e8 0f 01 c9 <e9> 7b ff ff ff 66 2e 0f 1f 84 00 00 00 00 0 621551] Stack: Press Ctrl+S to enter the Setup Menu..
