I got hold of a 2430sdp and saw the same behavior, however DEBUG_LL and earlyprintk worked and this is what I see [ 0.000000] Unable to handle kernel NULL pointer dereference at virtual address 00000000 [ 0.000000] pgd = c0004000 [ 0.000000] [00000000] *pgd=00000000 [ 0.000000] Internal error: Oops: 5 [#1] SMP ARM [ 0.000000] Modules linked in: [ 0.000000] CPU: 0 PID: 0 Comm: swapper/0 Not tainted 3.13.0-rc4-00056-ga9fa93e #2 [ 0.000000] task: c07dfcb8 ti: c07d4000 task.ti: c07d4000 [ 0.000000] PC is at clk_mux_get_parent+0x14/0xcc [ 0.000000] LR is at clk_mux_get_parent+0x10/0xcc [ 0.000000] pc : [<c044a234>] lr : [<c044a230>] psr: a00001d3 [ 0.000000] sp : c07d5f40 ip : 00000000 fp : 00000000 [ 0.000000] r10: c07dc880 r9 : 4107b366 r8 : c07f46a4 [ 0.000000] r7 : c0edfa80 r6 : ffffffff r5 : c07f6810 r4 : 00000002 [ 0.000000] r3 : 00000000 r2 : 00000000 r1 : c069da67 r0 : 00000002 [ 0.000000] Flags: NzCv IRQs off FIQs off Mode SVC_32 ISA ARM Segment kernel [ 0.000000] Control: 00c5387d Table: 80004000 DAC: 00000017 [ 0.000000] Process swapper/0 (pid: 0, stack limit = 0xc07d4248) [ 0.000000] Stack: (0xc07d5f40 to 0xc07d6000) [ 0.000000] 5f40: c044a220 00000002 c6001f40 c0448e54 c07dfcb8 c0862f7c c07f3600 c07f4368 [ 0.000000] 5f60: ffffffff c0edfa80 c07b6b80 4107b366 c07dc880 c077edf4 c0531008 c07f4380 [ 0.000000] 5f80: c07f34d4 c077f20c c0878964 c0edfa80 c07b6b80 c0877ac4 c0877640 ffffffff [ 0.000000] 5fa0: c0edfa80 c0777268 00000001 c07792ac c07b5250 c077221c 00000002 c076e974 [ 0.000000] 5fc0: ffffffff ffffffff c076e57c 00000000 00000000 c07b6b80 00000000 00c5387d [ 0.000000] 5fe0: c07dc928 c07b6b7c c07e1474 80004008 8052c544 80008074 00000000 00000000 [ 0.000000] [<c044a234>] (clk_mux_get_parent+0x14/0xcc) from [<c0448e54>] (__clk_init+0xe4/0x3f0) [ 0.000000] [<c0448e54>] (__clk_init+0xe4/0x3f0) from [<c077edf4>] (omap_clocks_register+0x24/0x48) [ 0.000000] [<c077edf4>] (omap_clocks_register+0x24/0x48) from [<c077f20c>] (omap2430_clk_init+0x4c/0x124) [ 0.000000] [<c077f20c>] (omap2430_clk_init+0x4c/0x124) from [<c0777268>] (omap_clk_init+0x28/0x30) [ 0.000000] [<c0777268>] (omap_clk_init+0x28/0x30) from [<c07792ac>] (omap2_sync32k_timer_init+0x8/0x58) [ 0.000000] [<c07792ac>] (omap2_sync32k_timer_init+0x8/0x58) from [<c077221c>] (time_init+0x1c/0x30) [ 0.000000] [<c077221c>] (time_init+0x1c/0x30) from [<c076e974>] (start_kernel+0x1d4/0x360) [ 0.000000] [<c076e974>] (start_kernel+0x1d4/0x360) from [<80008074>] (0x80008074) [ 0.000000] Code: e1a05000 e5900000 ebfff7f5 e595300c (e5933000) [ 0.000000] ---[ end trace 3406ff24bd97382e ]--- [ 0.000000] Kernel panic - not syncing: Attempted to kill the idle task!
