CFS (Cluster File System aka Lustre) appliance. As for why, I don't exactly know.
I'd have to fetch crash sources and see that is going on where that message
gets emitted.
No, I meant what was the dumpfile format, i.e., was it an ELF kdump,
compressed-kdump, Xen dump, kvmdump, etc?
The error message is from here, where the starting stack pointer
could not be determined, or was an address that is not accessible
for some reason:
if (!(bt->flags & BT_USER_SPACE) && (!rsp || !accessible(rsp))) {
error(INFO, "cannot determine starting stack pointer\n");
if (KVMDUMP_DUMPFILE())
kvmdump_display_regs(bt->tc->processor, ofp);
else if (ELF_NOTES_VALID() && DISKDUMP_DUMPFILE())
diskdump_display_regs(bt->tc->processor, ofp);
else if (SADUMP_DUMPFILE())
sadump_display_regs(bt->tc->processor, ofp);
return;
}
