Helo, i have reviewed which is really fascinating. The architecture i use : crash> sys KERNEL: /boot/vmlinux-2.6.15.2 DUMPFILE: /dev/mem CPUS: 1 DATE: Wed Mar 29 12:05:05 2006 UPTIME: 04:33:58 LOAD AVERAGE: 0.05, 0.06, 0.02 TASKS: 67 NODENAME: portable.domain.com RELEASE: 2.6.15.2 VERSION: #4 PREEMPT Tue Mar 21 14:34:11 CET 2006 MACHINE: i686 (748 Mhz) MEMORY: 511.9 MB A question : i could not find how to have a module withou [CONFIG_KALLSYMS] when i do mod

Some problems 1)kmem -s and kmem -S crash> kmem -s kmem: invalid structure member offset: kmem_cache_s_lists FILE: memory.c LINE: 7671 FUNCTION: do_slab_chain_percpu_v2() [./crash] error trace: 8099315 => 80a4d09 => 80a635d => 810cab0 CACHE NAME OBJSIZE ALLOCATED TOTAL SLABS SSIZE 810cab0: OFFSET_verify+81 80a635d: do_slab_chain_percpu_v2+103 80a4d09: dump_kmem_cache_percpu_v2+1615 8099315: cmd_kmem+3392 kmem: invalid structure member offset: kmem_cache_s_lists FILE: memory.c LINE: 7671 FUNCTION: do_slab_chain_percpu_v2() 2) crash> kmem -i PAGES TOTAL PERCENTAGE TOTAL MEM 128778 503 MB ---- FREE 44244 172.8 MB 34% of TOTAL MEM USED 84534 330.2 MB 65% of TOTAL MEM SHARED 45690 178.5 MB 35% of TOTAL MEM BUFFERS 4371 17.1 MB 3% of TOTAL MEM CACHED 51358 200.6 MB 39% of TOTAL MEM SLAB 0 0 0% of TOTAL MEM TOTAL HIGH 0 0 0% of TOTAL MEM The command stops and SLAB is certainly not correct

3) net -s and net -S crash> net -s net: invalid structure member offset: files_struct_max_fdset FILE: net.c LINE: 1117 FUNCTION: dump_sockets_workhorse() [./crash] error trace: 80dca66 => 80ded3a => 80def30 => 810cab0 PID: 5489 TASK: d7b97000 CPU: 0 COMMAND: "crash" 810cab0: OFFSET_verify+81 80def30: dump_sockets_workhorse+164 80ded3a: dump_sockets+80 80dca66: cmd_net+418 net: invalid structure member offset: files_struct_max_fdset FILE: net.c LINE: 1117 FUNCTION: dump_sockets_workhorse()

4) The problems withe those commands are normal i think, the structures are not supported in kernel 2.6? kmem -la, -La, -li, -Li do not find active_list and inactive_list irq -b net -a
