Hi, I am trying to debug a bug on SLES 10 kernel using crash. I have the vmlinux and the vmlinux.debug file for the corresponding kernel but when I try to start crash it hangs while loading the "slab cache" data. **** crash 4.0-7.2.3.el5_3.1 .... .... GNU gdb 6.1 .... This GDB was configured as "x86_64-unknown-linux-gnu"... please wait... (gathering kmem slab cache data) **** I then ran crash with "-d 99" debugging support. Looking at the debug data generated from crash, below is the text which is repeatedly printed by crash. ------ crash: invalid kernel virtual address: 47 type: "kmem_list3 shared" <readmem: ffff81000f6266c8, KVADDR, "kmem_list3 shared", 8, (ROE|Q), 7fff89fb1f00> <readmem: f88948c3c0310006, KVADDR, "shared array_cache limit", 4, (ROE|Q), 7fff89fb1f0c> crash: invalid kernel virtual address: f88948c3c0310006 type: "shared array_cache limit" FREEBUF(1) <readmem: ffff81000f5ab1a0, KVADDR, "kmem_cache_s buffer", 1648, (ROE), a5a480> <readmem: ffff81000f5ab1a0, KVADDR, "array cache array", 1024, (ROE), 7fff89fb1f10> GETBUF(512 -> 1) <readmem: ffff81000f5ab5b0, KVADDR, "array nodelist array", 512, (ROE), a57c80> <readmem: 47, KVADDR, "kmem_list3 shared", 8, (ROE|Q), 7fff89fb1f00> crash: invalid kernel virtual address: 47 type: "kmem_list3 shared" <readmem: 47, KVADDR, "kmem_list3 shared", 8, (ROE|Q), 7fff89fb1f00> ------ Is there a way to tell crash to skip loading slab data ? Or is this a known bug with crash on sles 10 ?

Please let me know what might be going wrong here. Thanks, Alok -- Crash-utility mailing list Crash-utility(a)redhat.com https://www.redhat.com/mailman/listinfo/crash-utility
