Dear All, I am using one SMP arm board if my one Application thread crash on one core(CPU0) and some time i observe second core generate(CPU1) the core dump.
when i observed the core dump file i observe gdb is show CPU1 register information. kernel crash messages:- Pid: 161, comm: thread CPU: 1 Not tainted (2.6.35.13 #19) PC is at 0x4002bb58 LR is at 0x4002bb90 pc : [<4002bb58>] lr : [<4002bb90>] psr: 20000010 sp : 40b82de8 ip : 40043000 fp : 40b82fac r10: 00000001 r9 : 43b8345c r8 : 00000000 r7 : 00000001 r6 : 40b834e0 r5 : 00000001 r4 : 00000000 r3 : 00000000 r2 : 00000001 r1 : 00000001 r0 : 00000000 (gdb) info reg r0 0x1 1 r1 0x0 0 r2 0x0 0 r3 0x1 1 r4 0x0 0 r5 0xf 15 r6 0x0 0 r7 0xf 15 r8 0xbeeb8878 3203106936 r9 0x0 0 r10 0x40025000 1073893376 r11 0xbeeb88b4 3203106996 r12 0x4002ce44 1073925700 sp 0xbeeb8870 0xbeeb8870 lr 0x8714 34580 pc 0x4002ce44 0x4002ce44 fps 0x0 0 cpsr 0x60000010 1610612752 Is this expected behavior ?
