Public bug reported:

I'm having trouble collecting more debug info for various reasons, but
I'm getting the following final bits with strace:

open("/sys/devices/system/node/node0/cpumap", O_RDONLY) = -1 ENOENT (No such 
file or directory)
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0x402268da8} ---
+++ killed by SIGSEGV +++
Segmentation fault

Is there a way to manually analyze a core file with apport?
