Re: [Crash-utility] Question for ARM developers/users w/respect to makedumpfile

Dave, I have a development board you can borrow. It runs fedora 15 armv5tel.

And if the original ARM /proc/vmcore was created incorrectly, then crash would seemingly have a problem pulling out the vmcoreinfo data from an ARM ELF kdump -- but it works just fine with those. I don't have any kind of ARM development environment in which to debug makedumpfile. So for now I'm going to put a horrific ARM-only kludge in the crash utility to look for the "OSRELEASE=xxx" string in the kdump sub_header block, and assign the size_vmcoreinfo and offset_vmcoreinfo values by hand. The "VMCOREINFO" string itself, which is in the ELF note header just prior to the actual data, is also missing.

OK thanks -- Per doesn't have any either, so maybe Jan does?
