[Crash-utility] snap crash plugin on RHEL 4

Dear crash-utility list, I played a bit with snap on RHEL 4 and besides the fact it doesn't build out of the box (trivial Makefile compatibility problem), it seems it doesn't really dump a full core properly (at least on the system I tested). Since this is not really something that is supposed to be supported I am posting this here rather than opening a Bugzilla. I haven't attempted to repro on other distros. # crash crash> extend snap-rhel4-x86_64/snap.so ./snap-rhel4-x86_64/snap.so: shared object loaded crash> snap mycore mycore: [100%] -rw-r--r-- 1 root root 4160684848 Sep 3 09:37 mycore crash> quit # free total used free shared buffers cached Mem: 16319168 8065516 8253652 0 133060 6231128 -/+ buffers/cache: 1701328 14617840 Swap: 2097144 0 2097144 # uname -a Linux *** 2.6.9-89.ELsmp #1 SMP Mon Apr 20 10:33:05 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux # crash /usr/lib/debug/lib/modules/2.6.9-89.ELsmp/vmlinux mycore [...] crash: read error: kernel virtual address: 1020009d024 type: "tss_struct ist array" Is that expected? Any idea what's going on? Thanks, Adrien
