Hi, I tried the latest crash tool 6.1.1 (built from sources) on a kernel 3.6.10 dump and it failed while reading the module information. Error says: crash: invalid structure member offset: module_core_size FILE: kernel.c LINE: 2974 FUNCTION: module_init() [../../crash-6.1.1/crash] error trace: 809afc6 => 810ecab => 8152543 => 80929f9 80929f9: OFFSET_verify.part.27+71 8152543: OFFSET_verify+51 810ecab: module_init+939 809afc6: main_loop+214 Even if I disable the the modules information gathering (--no_modules) it fails later on while trying to read the idle tasks: crash: cannot determine idle task addresses from init_tasks[] or runqueues[] crash: cannot resolve "init_task_union" Is this a known issue? Any plans to support kernel 3.6.10? As a FYI, I can use --minimal to enter the system and retrieve the dmesg buffer at the crash point.
