Try this patch on top of the previous one and post the dmesg with them applied. reg_table->last should not be 0. You should be seeing something like (slightly different per asic): [ 96.516683] 0 s1 = 0x0a2f pre_reg_data = 0x04 [ 96.516696] 1 s1 = 0x0a30 pre_reg_data = 0x00 [ 96.516710] 2 s1 = 0x0ad5 pre_reg_data = 0x04 [ 96.516723] 3 s1 = 0x0a28 pre_reg_data = 0x04 [ 96.516736] 4 s1 = 0x0a29 pre_reg_data = 0x04 [ 96.516746] 5 s1 = 0x0a2a pre_reg_data = 0x04 [ 96.516759] 6 s1 = 0x0a2b pre_reg_data = 0x04 [ 96.516772] 7 s1 = 0x0a2c pre_reg_data = 0x04 [ 96.516786] 8 s1 = 0x0a81 pre_reg_data = 0x04 [ 96.516798] 9 s1 = 0x0a8b pre_reg_data = 0x04 [ 96.516811] 10 s1 = 0x0a5f pre_reg_data = 0x04 for the first loop in the dumper. -- You are receiving this mail because: You are the assignee for the bug.
