Re: [Crash-utility] Crash fails for 2.6.19.2 kernel

I tried to use crash on a 2.6.19.2 dump, but it failed with the

crash: cannot resolve "system_utsname"
I found that there is no longer a symbol by that name in 2.6.19.2. It
appears to be referenced by init_urs_ns->name, but I didn't investigate
fully. The important issue for me is that crash doesn't work.

What version of crash? The crash changelog refers to a fix
for that quite some time ago:
4.0-2.31 - Bumped crash-internal NR_CPUS for x86 and ia64; added a warning
message to "recompile crash" and forced an initialization failure
when the kernel's configured NR_CPUS is greater than the maximum
allowed NR_CPUS value compiled into crash.
(maneesh(a)in.ibm.com, anderson(a)redhat.com)
- Fix for initialization failure indicating a kernel/memory-source
mismatch when x86 kernel configures its physical memory start
address higher than the traditional 1MB starting point.
(anderson(a)redhat.com)
- Fix for kernels that have replaced the "system_utsname" data
structure with contents of the "init_uts_ns" data structure.
This fixes a "crash: cannot resolve system_utsname" initialization
failure. (pbadari(a)us.ibm.com, anderson(a)redhat.com)
