Your crash version is remarkably old -- 3+ years old -- and it's always worth your while to update to the latest version. Maybe, maybe not... Seek errors are meant to indicate that, after the translation from kernel virtual address to physical address to the dumpfile location ended up with a dumpfile offset that was either: (1) not accessible, or (2) the physical page associated with the virtual address was not found in the dumpfile. I can't really help you with LKCD particulars, and like I mentioned above, I don't know what the "mini kernel dump" version of LKCD is, but I do note above that the dumpfile is being recognized as version LKCD_DUMP_V8. And http://people.redhat.com/anderson/crash.changelog.html contains this change to 4.0-2.17 that fixed something in your version 4.0-2.15: 4.0-2.17 - Fix to resurrect LKCD version 8 support, inadvertently broken in 4.0-2.15. (troy.heber(a)hp.com) - Fix for "net -S" failures in certain 2.6 kernels that failed with "net: cannot determine what an inet_sock structure is" message; shows embedded sock structure instead of failing. (anonymous donor) - Fix for erroneous "net -s" source/destination address and port values in certain 2.6 kernels; added "net -s" source/destination address and port values for IPv6 sockets. (anderson(a)redhat.com) (12/16/05) 4.0-2.16 - Fix for the x86_64 backtrace code to search all of the exception stacks for the origin of the active tasks' backtrace when the information is not available in the dumpfile header. Up until now, the search was made in the process stack, the per-cpu IRQ stack, and the per-cpu NMI exception stack; this patch looks at all 3 exception stacks in 2.4 kernels (NMI, STACKFAULT and DOUBLEFAULT), and all 5 exception stacks in 2.6 kernels (NMI, STACKFAULT, DOUBLEFAULT, DEBUG and MCE). - Fix to remove erroneous warning message re: the task cpu not being the same as the IRQ or exception stack cpu, which was displayed when doing a non-context-sensitive "bt -E" on an x86_64. (12/12/05) 4.0-2.15 - Applied Kurt Rader's (kdrader(a)us.ibm.com) patch for SUSE SLES 9 "bigsmp" kernel LKCD dumpfiles, to fix "conflicting page" abort caused by a dumpfile header that is larger than the formerly hard-wired header size. - Fix for ppc64-only segmentation violation when running "bt" on the panic task when run against a dumpfile created by the diskdump facility's new compressed format. (12/02/05) Perhaps upgrading to the latest version (4.0-7.7) will help? Dave
